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.

The solution depends on how many numbers are missing and where they were. If there is only one, If it is between 4 and -5 then -0.5 If it is between -5 and -10 then -8 If it is between -10 and -16 then -13 Of course, the answer would be different if there were more than one number missing.
This question cannot be answered for two main reasons. The first is that you have not specified where, in the sequence, the missing number is meant to be. Clearly that makes a difference.Suppose you assume the missing number is the last in the sequence, then any number that you choose can be the next number. It is easy to find a rule based on a polynomial of order 6 such that the first six numbers are as listed in the question followed by the chosen next number. There are also non-polynomial solutions. Short of reading the mind of the person who posed the question, there is no way of determining which of the infinitely many solutions is the "correct" one. The same applies, wherever in the sequence the missing number was meant to be.

The missing number is 26. The number after 29 is 58.
7 6,7,8,9,10
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.
The sequence consists of the squares of consecutive integers: (1^2 = 1), (4^2 = 16), (10^2 = 100), and (13^2 = 169). The missing number corresponds to (7^2), which is (49). Therefore, the missing number in the sequence is (49).
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.
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.

There are infinitely many possible answers. If the missing number is the second in the sequence, it could be part of an arithmetic progression and so equal 10.4, or it could be in geometric progression and so would be 4, or harmonic progression which would give 1/0.65 = 1.54, approx. Furthermore, he missing number cold be the first or third in the sequence.
