Find:10th term of the A.P. $1, 4, 7, 10, ………$

Given:

Given A.P. is $1, 4, 7, 10, ………$

To do:

We have to find the 10th term of the given A.P.

Solution:

Here,

$a_1=1, a_2=4, a_3=7, a_4=10$

Common difference $d=a_2-a_1=4-1=3$

We know that,

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

Therefore,

10th term $a_{10}=1+(10-1)3$

$=1+9\times3$

$=1+27$

$=28$

The 10th term of the given A.P. is $28$.
