Answer 2

$\huge{ \mathrm{ \star{ \underline{ \underline{ \red{Question...}}}}}}$

$\large{ \mathrm{ \bullet{ \: find \: value \: of \: n \:. ? }}}$

$\huge{ \mathrm{ \star{ \underline{ \underline{ \blue{Answer...}}}}}}$

$\large{ \mathrm{ \bullet{ \: = \: 27 }}}$

$\huge{ \star{ \underline{ \underline{ \red{ \mathrm{Solution....}}}}}}$

$\begin{lgathered}⟹\ an = \ a + (n - 1)d \\ \\⟹ \ 82 = \ 4 + (n - 1)3 \\ \\⟹ \ 82 - 4 = \ 3n - 3 \\ \\⟹ \ 78 + 3 = \ 3n \\ \\⟹ \ 81 = \ 3n \\ \\⟹ \ n = \ 27\end{lgathered}$

$\therefore{ \orange{ \mathrm{ \large{ \underline{ \underline{ \: required \: answer \: is \: 27}}}}}}$
