Well, darling, the nth term for this sequence is 8n + 7. You just add 8 to each term to get the next one, simple as that. So, if you want the 100th term, just plug in n=100 and you'll get 807. Easy peasy lemon squeezy!
2n^2-1
+9
a (sub n) = 35 - (n - 1) x d
Type your answer here... The next numbers in the sequence are 55, 70, 87, 106, 127, etc.
The nth term is 7n-4 and so the next number in the sequence is 31
