Question

The first term of an $A.P$ is $p$ and its common difference is $q$. Find its $10th$ term

Answer 1

Given that,

First term of an A.P. is $\left(a\right)=p$

Common difference $d=q$

Find its ${10}^{th}$ term.

We know that,

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

$a_{10}=p+(10-1)q$

$a_{10}=p+9q$

Hence, ${10}^{th}$ term is $p+9q$.
