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 $28$.
