(2)² = 4

(8)² = 64

(5)² = 25

(1)² = 1.

(10 + 9 + 14 + 7)/2 = 20

and (11 + 16 + 10 + 13)/2 = 25

Therefore, (15 + ? + 12 + 10)/2 = 22

Hence 37 + ? = 44

? = 44 - 37

? = 7.

(5 x 6) + 2 = 32

(7 x 6) + 2 = 44

(7 x 5) + 2 = 37.

(5 + 3)/2 = 4

and (6 + 8)/2 = 7

Therefore (8 + 4)/2 = 6.

(1)² + (5)² + (4)² + (3)² = 51 x 10 = 510

and (3)² + (4)² + (6)² + (2)² = 65 x 10 = 650

Similarly (0)² + (1)² + (2)² + (8)² = 69 x 10 = 690.

1 + 2 + 3 + 4 = 10

and 1 + 3 + 5 + 8 = 17

Similarly, 1 + 4 + 6 + 9 = 20.

(4 + 8) x 9 = 108

(5 + 4) x 12 = 108.

For first triangle,

10 - 4 = 6

18 - 10 = 8

18 - 4 = 14

For second triangle,

14 - 8 = 6

22 - 14 = 8

22 - 8 = 14

For third triangle,

11 - 5 = 6

15 - 11 = 4

15 - 5 = 10.

(2 x 2 - 1) = 3

and (5 x 4 - 5) = 15

(5 x 5 - 3) = 22.

How the number is obtained?

2 + 4 = 6

5 + 9 = 14

Similarly,

3 + 5 = 8

Therefore, the answer is K8.
