what are finite and non finite sets |
| Answer» As the name represents, the finite set is a set having finite or countable number of elements.Example set of all English alphabets.A set which is not a finite set is called an Infinite Set.

Find the sum of integers from 1to2001 |
|
Answer» Or u can use the second formula for calculating sum which is-Sn=n/2[a+l]So,from above u can see yogita has already finded the value of n which is 1001 and here u have l=2001 so,Sn=1001/2[1+2001]=1001*1001=1002001. #Ans 2003001 In this question AP has been formed, which is 1,2,3,4,5,.....,2001, in which a = 1, d = a2-a1 = 2-1 = 1, l = 2001, n = 2001S2001 = n/2(a+l) =2001/2(1+2001) =2003001, Answer Hence, the sum of integers from 1 to 2001 is 2003001. The odd integers from 1 to 2001 are 1, 3, 5, …1999, 2001.This sequence forms an A.P.Here, first term, a = 1Common difference, d = 2Here, |
