Question

In an AP, if a = 3.5, d = 0, n = 101, then an will be

Answer 1

3.5

Given, a = 3.5

Common difference , d = 0 , So nothing will be added to the first term and hence every element of the A.P will be same as the first element.

Answer 2

an= a + (n-1) d

Given:

a=3.5

d=0

n=101

an=3.5+(101-1)0

= 3.5+(100×0)

=3.5

an=3.5
