Question

Find next two terms of an A.P.
$4,9,14,$ __________.

Answer 1

First Term, $a=4$

Common difference, $d=5$

nth term is given by,

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

Fourth term $=$ $4+(4-1)5=15+4$ $=19$ ........ $n=4$

Fifth term $=4+(5-1)5=20+4$$=24$ ........... $n=5$

Next two terms are $19$ and $24.$
