In an AP, if a = 3.5, d = 0 and n = 101, then an will be
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 its an constant A.P. therefore its all terms will be equal and constant)
