Find the sum of the first thirty terms of the sequence:
1, 5, 6, 11, 17, 28
if the 30th term is 2888956 and the 31st term is 4674429
I figured the pattern was tn = tn-1 + tn-2
so the first term would be a, then b, a+b, a+2b
basicly the Fibonacci Sequence. Is there away to do the question without have to list the Fibonacci Sequence up to it's 30th term?
