Answer 1

ANSWER✔

$\large\underline\bold{GIVEN,}$

$\sf\dashrightarrow a_n=3_n+1$

$\sf\dashrightarrow a_n+1$

$\large\underline\bold{TO\:FIND,}$

$\sf\dashrightarrow THE\:VALUE\:OF\:a_n+1$

$\large\underline\bold{SOLUTION,}$

$\sf\dashrightarrow a_n= 3_n+1\:--[given]$

$\sf\therefore a_n+1=?$

$\bf\therefore \red{\:putting \:value \:of\: a_n \:in\: the\: above \:equation. we \:get,}$

$\sf\implies (3_n+1)+1$

$\sf\implies 3_n+1+1$

$\sf\implies 3_n+2$

$\large{\boxed{\bf{ \star\:\:3_n+2\:\: \star}}}$

$\large\underline\bold{THEREFORE\:A_n+1\: is\: \implies 3_n+2}$
