Question

If 3+4=11,4+9=19,5+36=31,7+25=?

Answer 1

Step-by-step explanation:

3+4=11

4+9=19

5+36=31

7+25=32

Answer 2

Missing number (?) = 54

Step-by-step explanation:

We have,

3 + 4 = 11, 4 + 9 = 19, 5 + 36 = 31

To find, 7 + 25 = ?

The pattern follow:

$(First number)^{2}+\sqrt{Second number}$

3 + 4 = 11

$3^2$ + $\sqrt{4}$ = 9 + 2 = 11

4 + 9 = 19

$4^2$ + $\sqrt{9}$ = 16 + 3 = 19

5 + 36 = 31

$5^2$ + $\sqrt{36}$ = 25 + 6 = 31

Similarly,

? = $7^2$ + $\sqrt{25}$ = 49 + 5 = 54

∴ Missing number (?) = 54
