The answer will depend on where in the sequence the missing number is:
Using only quartic polynomials, the solutions are:
3, 10, 25, 54, 103
10, 11.75, 25, 54, 103
10, 25, 33.8333..., 54, 103
10, 25, 54, 84.25, 103
10, 25, 54, 103, 178.
Other functional forms will generate many more answers.
The missing number is 26. The number after 29 is 58.
The sequence appears to be made up of the squares of consecutive integers: (1^2 = 1), (4^2 = 16), and (10^2 = 100). The missing number corresponds to (7^2), which is (49). Therefore, the missing number in the sequence is 49.
17-12n 17-12(10)=-103
To find the missing number in the sequence 10, 15, 28, we can look for a pattern in the differences between the numbers. The difference between 10 and 15 is 5, and the difference between 15 and 28 is 13. If we assume a pattern in the differences, the missing number could be 21, which fits as the average of 15 and 28. Thus, the sequence could be 10, 15, 21, 28.
c) 17
The missing number is 26. The number after 29 is 58.
178 is the answer By using the formula a{n} = n³ + n² + 5n + 3 For e.g. A{2} =2 ³ +2²+5*2+3=25 =8+4+10+3=25 And so on.    = 10, 25, 54, 103, 178

Dodging numbers may be missing numbers in a sequence. For example, the underscore in the following sequence represents such a number: 2, 4, _ , 8, 10.

17-12n 17-12(10)=-103
10 (between 7 and 13)
16
c) 17
To determine the missing number in the sequence 20, 0.8, we need to identify the pattern. One possible pattern is that each number is being divided by 10. In this case, 0.8 divided by 10 equals 0.08. Therefore, the missing number would be 0.08.
