${\pink{\huge{4}}}$

⭐${\blue{\huge{Explanation}}}$⭐

If you take the two numbers in block as a and b, the operation performed with them is a² + b² + 2 to get the number.

In first block,

3²+2²+2 = 9 + 4 + 2 = 15

In second block,

4²+7²+2 = 16 + 49 + 2 = 67

In third one,

3²+8²+2 = 9 + 64 + 2 = 75

Similarly in 4th one, let the missing number x

6²+x²+2 = 54

36+x² = 52

x² = 16

x = √16

x = 4
