In Problems 21-28, find the numerical value of the given sum. $$ \sum_{k=1}^{20} 2 k $$

In this problem, the mathematic preparation rules like this, clearly the first storm E is bring the five common difference. City is difference between any two consecutive numbers. So let's take the second and the first, which is D -25, which is Andy now we know that the Senate tome has given us A plus and -1. And today, Now in the end of a term that has given us 1000 says equals to 25 plus & -1. Indeed, 25 Taking 25 common, This is one plus and minus one, Which is nothing but 25. And to end this is 1000. So and it's nothing but 1000 25 which is 40. So it's the 14th time, that's all.

Here we have to find the some off cities given by summation off 1.14 K minus self. 2.8 were gave. It is from 100 and one blunder minus off. Submission K is equal to one 25 and the term is shapeless off. Four Ah born then. So the hair we have two parts off this emission live in Seoul. One Bevan part off this emission and then we will add these parts. So taking first part here, start with it. Substituting K is equal to 100 and one. We will get first term as 100 and one is equal to 1.14 in tow, 101 minus off 2.8. So this will be equal to 115 minus off. 2.8 is a Gordo 112.34. So this will be our even now that if we have to find the 8 200 this will be Quito. One might run for in Toto 100 minus off. No point it. This will be Quito. 220. It minus off 2.8 is equal to 225 point off to now we have even or we can say n 801 and A 200 will be quarto from 100 to 200. We will have a musical 200 so the some of the terms will be given by as often is a quarto and upon toe a of 101 plus a off 200. This will be quick dough 100 of bone do indoor 112.34 plus off 25 point toe. This will be called OH 50 indoor 100 12.34 plus off Road 25 fired too. And this some will be Quito 50 indoor 337 0.54. This will be cool. 16,877. No, we will find the some off Second city is given by a K plus Ford by attend where K varies from 1 to 5. So for the second, cities even will be given by K plus four button means one plus, for this will be quarto five by 10 Here in will be is equal to a five, which will be Quito K plus for Means five plus +49 upon 10 some off items as five will be given by five upon toe a place off in five by 10 plus off nine by and this will be quarto five upon to and do for Dana Bone. Then this will be Quito. Seven upon two is equal to 3.5. Hence, the total time will be given by 16,877 minus off 3.5. This will be Quito 16,800 73.5, So this will be the required solution for the given some off cities.

So we see that under some his stuff from the cake to one? Absolutely. Could you far So 20 dude isn't by medically. So when Kai ico to one can go to to thank you 23 Okay. Could you far, So we should have him. Would be. You're anchored to one Uganda canyon size and gonna one ministry times going toe wonders do you go to? We're gonna modesty au temps tree will be minus six. I could eat you. So to ministry attempt with the job less Joe. So you go to minus one times far will be minus far and trick a budgetary. So three minutes street hams go in that dreary Bless Joe Johnny coaches era and can't get you far, far minutes three times going toe for us, Joe. So you go Jew one times six, maybe six. So we with a line And when we do the ambition now So we got minus six with the six counsel I would never have only the equal to minus far. And this would be the answer

Here we have to find the some of the city's given by submission off. 2000 minus self three k. They're Kayla is from To Do 50 now to find the sum first vehicle right out a few times off the given cities massive saluting to We will have the first time as 1994 and then 1991 1988 and so on. So the same is given way as an easy Gordo. And upon do and go to a place off and minus one in tow. Really? We have even here defense can be Find out. Bay DVB quarto eight to minus off. Evan, this will wake Weirdo 1991 minus off 1994 which will be quarto minus off three. So we have defense also now and inconvenient Remained by hair. The terms are starting from two. So we are left here one. So we have in propel a £49 from cool to 50. Exclude England. We will have 49 dems. So executing the values we can right here and is equal to 14. A central beak weirdo 49 upon to in tow. Fluffy means 1994 and go to this will be equal to 3988. Bless off and minus one means 48 in two d Minor self three. So this week, weirdo 49 upon door indoor 3988 minus off 1 40 four Corded. This will be quarto 49 upon to indoor 3844 canceling toe here on multiplying 49. With this, we will get 94,170 it as the some off the given cities.
