Answer:

Step-by-step explanation:

Given : A.P. = 7,10,13...

To Find: Which term is 151?

Solution:

First term = a = 7

Common difference = d= 10-7=13-10=3

Formula of nth term = $a_n=a+(n-1)d$

Where a is the first term

d is the common difference

Now to find the term no. of 151

$151=7+(n-1)3$

$144=3n-3$

$147=3n$

$49=n$

Thus 151 is 49th term of given A.P.
