Answer 1

answer is 66

......

5+6+2 = 13

5+8+2(4) = 21

9+7+5(10) = 66

Answer 2

The missing number (?) = 46

Step-by-step explanation:

To find, the missing number (?) = ?

The pattern follow,

The squaring and addind of  outsides the three number ÷ 5 = Inside number

In figure 1,

13 = $\dfrac{5^2+6^2+2^2}{5}= \dfrac{25+36+4}{5}$

= $\dfrac{65}{5}$ = 13

In figure 3,

21 = $\dfrac{8^2+4^2+5^2}{5} =\dfrac{64+16+25}{5}$

$=\dfrac{105}{5}$ = 21

Similarly,

In figure 2,

?  $=\dfrac{7^2+10^2+9^2}{5} =\dfrac{49+100+81}{5}$

= $\dfrac{230}{5}$ = 46

The missing number (?) = 46

Thus, the missing number is 46.
