Question

9+1=91, 8+2=75, 7+3=61, 6+4=49, 5+5=39, 3+7=?

Answer 1

We can note the following pattern:

$\begin{gathered} 9^2+1+9=81+10=91 \\ 8^2+2+9=64+11=75 \end{gathered}$

and

$7^2+3+9=49+12=61$

Similarly,

$\begin{gathered} 6^2+4+9=36+13=49 \\ 5^2+5+9=25+14=39 \end{gathered}$

So, our pattern matches with the given results.

By applying this pattern to the question, we have

$3+7\Rightarrow3^2+7+9=9+16=25$

Therefore, the answer is: 7+3=25
