Question

Find the 10th term of the AP 1,4, 7, 10….

Answer 1

In this problem, we are given different A.P. and we need to find the required term of that A.P.

10^th term of the A.P. 1,4, 7, 10….

Here

First term (a) = 1

Common difference of the A.P. (d)  = 4 - 1

= 3

Now, as we know,

`a_n  = a + (n - 1)d`

So, for 10^th term,

`a_10 = a + (10 - 1)d`

`= 1 + (9)3`

= 1 + 27

= 28

Therefore, the 10^th term of the given A.P. is `a_10 = 28`
