(4)² + (2)²+ (1)² = 21

(5)² + (3)²+ (8)² = 98

(6)² + (4)²+ (3)² = 94

Hence, the required number is 94

Find the missing number in the following figure

15	6	5
13	3	9
8	2	?
20	7	13

15+13-8 = 20

6+3-2 = 7

5+9-x = 13

Therefore, x = 1

Hence, the required number is 1

Find the missing number in the following figure

1	3	7
5	12	14
25	?	28
