The answer can be derived from the sum of the top and bottom rows.
The puzzle has one more trick up it's sleeve though as 3+2 doesn't equal 6....
Keep trying!
The missing number is 49. This is why: 1 plus 2 equals 3, then 3 squared is 9. 2 plus 3 equals 5, then 5 squared is 25. Therefore, the missing number must be 49 to make the number sentence (3 plus 4 equals 7, then 7 squared is 49) true.

Number is 11.1 (+1) 2 (+2) 4 (+3) 7 (+4) 11 (+5) 16 ...
I think 8
0 is the missing number.
The first five prime numbers starting from 1 are 1, 2, 3, 5, 7. So 2 is the missing number.

Assuming that you are referring to 1 whole and not one hole, the answer would seem to depend on what operation (addition, subtraction, etc) with the missing number is involved.
The missing number is 1321!!! Simple Fibonacci row! 0+1=1 1+1=2 1+2=3 2+3=5 3+5=8 5+8=13 8+13=21 13+21=34 ......
Missing number is 256 The series is 1,4,27,256,3125 i.e. 1, 2*2, 3*3*3, 4*4*4*4, 5*5*5*5*5
Number is 11.1 (+1) 2 (+2) 4 (+3) 7 (+4) 11 (+5) 16 ...

49 The sequence is the squares of numbers that increase by 3 each time: 1² = 1 (1 + 3 )² = 4² = 16 (4 + 3)² = 7² = 49 (7 + 3)² = 10² = 100 (10 + 3)² = 13² = 169
0 is the missing number.
In numerical order, with no missing numbers. 1, 2, 3, and 4 are consecutive. 1, 3, 4, and 2 are the same numbers, but are not consecutive because they are not in order. 1, 3, and 4 are not consecutive because 2 is missing.
