Q2 of 38 Page 5

In an AP, if a = 3.5, d = 0 and n = 101, then find the value of an.

Given: a = 3.5, d = 0 and n = 101


To find: The value of an.


Formula Used: nth term of an AP is:


an = a + (n - 1) d


Explanation:


As we know, nth term of an AP is


an = a + (n - 1) d


where a = first term


an is nth term


d is the common difference


an = 3.5 + (101 - 1 )0


= 3.5


(Here we have given d = 0, therefore it’s a constant A.P. therefore it’s all terms will be equal and constant)
