If the $n^{th}$ term of an AP is $\frac{3+n}{4}$, then find its $8^{th}$ term.
Given: $n^{th}$ term of an AP is $\frac{3+n}{4}$
To do: To find its $8^{th}$ term.
Solution:
If $n^{th}$ term is $\frac{3+n}{4}$
$\therefore 8^{th}\ term=\frac{3+n}{4}$
$=\frac{3+8}{4}$
$=\frac{11}{4}$
Thus, $8^{th}$ term of the A.P. is $\frac{11}{4}$.
