What is the next term ?
61 , 52 , 63 , 94 , 46 , ??
Hi
I think the answer is 18, because
$\displaystyle 4^2 = 16 \Rightarrow 61$
$\displaystyle 5^2 = 25 \Rightarrow 52$
$\displaystyle 6^2 = 36 \Rightarrow 63$
$\displaystyle 7^2 = 49 \Rightarrow 94$
$\displaystyle 8^2 = 64 \Rightarrow 46$
$\displaystyle 9^2 = 81 \Rightarrow 18$
Yours
