Step-by-step explanation:

Given series is 7, 8, 12, x, 37, 62. find x?

8–7 = 1 = 1 * 1

12–8 = 4 = 2* 2

x - 12 = ?

37 - x = ?

62 - 37 = 25 = 5 * 5

as we see the common difference between consecutive two numbers are,

1^2, 2^2, 5^2, thus remaining 2 will be 3^2, 4^2

=> x—12 = 9

=> x = 21. Ans
