Oh, what a happy little sequence we have here! It looks like we're adding 8, then subtracting 7, then adding 14. Sometimes sequences can be a bit unpredictable, but that just makes them more exciting to figure out. Just remember, there are no mistakes in sequences, only happy little surprises.

Is this sequence arithmetic 12 19 26 33 if so what is the common difference?
7
What is the sum of the first 33 terms of the following sequence 8 17 26?
5016. Here's how: Each term is 1 less than the terms in 9, 18, 27 ..., which is the sequence 9*N, with N = 1..33. So the actual formula for the sequence is {9*N - 1} The sequence 1,2,3...N can be summed by (N+1)*N/2 --> N=33: (33+1)*33/2 = 561, so the sum of the first 33 terms of 9+18+27+297 = 9*(1+2+3+..+33) = 9*561 = 5049. But our sequence terms are each one less than the terms in 9,18,27, so subtract 33 from 5049 = 5016.
