The next number in the sequence is 15. The pattern is as follows: from 1 to 6 is +5, from 6 to 9 +4, from 9 to 12 +3, from 12 to 14 +2, and then from 14 to the answer (15) +1.

The number that comes next in the series 1 2 2 5 3 10 is 7. You get this number by subtracting the number 3 from the number 10.

Seems to be a '+1, +2' sequence, so 12 would be next.

9 the pattern is you subtract 3 and for the next number you add 1

21 - each number in the series increases by the series 1,2,3,4,5.... Whereby 6 and 7 are separated by 1, 7 and 9 are separated by 2, 9 and 12 are separated by 3, 12 and 16 are separated by 4, so the next in the series would be 21 (16 and 21 are separated by 5).

This series is of the function f(x) = x2+1, starting with x=0.The next number in the series is 26. The number after that is 37.

1Another AnswerEach number of the series appears to double as the series progresses: 1/12 (x2), 1/6 (x2), 1/3 (x2), 2/3, etc. This being so, the next number in the series would be 4/3 or 1-1/3 (2/3 x 2)..

The series goes like this 2 = 1^2 + 1^3 (1 square + 1 cube) 12 = 2^2 + 2^3 36 = 3^2 + 3^3 and so on.. So, the next number in the series is 6^2 + 6^3 = 252.

The next number is -21

These are squares. 12 = 1 22 = 4 32 = 9 (it is missing 42 = 16) 52 = 25 62 = 36 The next one in the series is probably 72 = 49.

The next number is 243, because 81x3=243.

The pattern is +1, +2, +1, +2, so the next number will be 10 (9 + 1).
