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.
Well, honey, looks like we've got ourselves an arithmetic sequence here with a common difference of 7. So, to find the nth term, we use the formula a_n = a_1 + (n-1)d. Plug in the values a_1 = 12, d = 7, and n to get the nth term. Math doesn't have to be a drag, darling!

The 'n'th term is [ 13 + 5n ].

yes, d = 7

One fourth of the bones in our body are in our feet.
mean = (17 + 43 + 19 + 8 + 26 + 33 + 8) ÷ 7 = 22
There seems to be a number missing between 78 and 213. Please check and resubmit.
27 and 1/3
Is this a next in the sequence thing? Any reason why the obvious 24 has been ignored? +5 -2
