Question

Determine the ninth term in the sequence whose nth term

Answer 1

SOLUTION

The nth term of the sequence is:

$a_n=4n+7$

To find the ninth term, substitute n=9 into the equation, it follows:

$\begin{gathered} a_9=4(9)+7 \\ a_9=36+7 \\ a_9=43 \end{gathered}$

Therefore the ninth term is 43.
