The pattern appears to be that n1 is defined as 25; n2 = n1 + 3; n3 = n2 - 4 = n1 - 1. If this is the pattern, the next number would be 25. If this is the pattern, the series would repeat endlessly: 25, 28, 24, 27,23, 26, 22, 25, , 28, 24, 27,23, 26, 22, ...

The answer is 109. 21 + (1 x 28) = 49 22 + (2 x 28) = 78 25 + (3 x 28) = 109
