Solution

We have been given an arithmetic progression where
a = 4, d = 1(4) =3 and an = 101
We need to find which term of the given AP is 101 so, we need to find n.
Using an = a + (n 1)d
Substituting the values in the formula we get
101 = 4 + (n1)3
101+ 7 = 3n
3n =108
n =36
Therefore, 36th term of given A.P is 101.
