3 4 5 6 The next number is 1 plus the previous number So the pattern rule is the next number is n + 1
the answer is 72.:)
21: (3)+3=(6)+4=(10)+5=(15)+6=(21)

10.1(+2) 3 (+3) 6 (+4) 10

The next number could be 25. +3, +6, +9, +12 etc.
For an integral sequence the next number is 6 (add 5 subtract 7 pattern).
The next number is 116.
The pattern appears to be: subtract 6, add 17, subtract 14, add 9, subtract 7. Following this pattern, the next number should be obtained by adding 3 to the last number in the sequence, which is 6. Therefore, the next number in the sequence is 9.
The next number is 39. The position to value rule is: Un = (7n4 - 89n3 + 392n2 - 694n + 438)/6 for n = 1, 2, 3, ...
It is 15 followed by 6 then 18
