is 219 in the sequence of 4n-3

29

The missing number is 26. The number after 29 is 58.

It is: nth term = 29-7n

The answer depends on the function used to generate the sequence. If the function is Un = (n3 - 3n2 + 8n - 3)/3 for n = 1, 2, 3, ... from which U5 = 29 or Un = 2n - 1 which would imply the next number is 31. There are other possible answers.

Since the number 29 is prime, the greatest common factor of 15 and 29 is 1.

The sequence of differences between consecutive numbers is 9, 1, -20, 9, 1. If this continues then the next difference is -20 and therefore the seventh number is -5. (15 - 20).
