0 is the missing number.
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.

The number progression is n+prime numbers progressively increasing starting from 2. The missing number is 29.
The first five prime numbers starting from 1 are 1, 2, 3, 5, 7. So 2 is the missing number.
The missing number is 5. When a number is divided by 3, the remainder is 2. So, the number can be represented as 3n + 2, where n is an integer. If we add 3 to this number, the remainder will be 1. Therefore, the missing number is 3n + 2 + 3 = 3n + 5, where n is an integer.
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.

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
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.
