We are to complete the addition in base seven

$\begin{gathered} 24_{\text{seven }} \\ + \\ 65_(seven) \\ ---- \\ ---- \end{gathered}$

Computing the first part

$4_{\text{seven}}+5_{\text{seven}}=9_{\text{ten}}$

Converting base 10 to base 7

This gives

$9_{\text{ten}}=1*7+2*1=12_(seven)$

Hence

$4_{\text{seven}}+5_{\text{seven }}=12_(seven)$

Therefore the answer is

$12_{\text{seven}}$
