It is possible to find a polynomial of degree 5 such that it can be made to fit the pattern of the above five numbers and any number at all that is chosen to be the eighth.
However, the simplest polynomial of degree 4 is
Un = 36n4 - 336n3 + 1128n2 - 1568n + 741 for n = 1, 2, 3, ...
and accordingly, the 8th term is 35,813.
It is 917969.
90
The 8th term is 64. The sequence is the squares of the counting numbers. The nth term is given by t(n) = n².
It is: 1 1 2 3 5 8 13 and 21 which is the 8th term
The eighth term of the series 4, 8,16,32 is 512. Each term is twice the previous term.
It is 917969.

77
The formula is 6n + 7 where n is the nth term So 8th term would be (6 x 8) + 7 = 48 + 7 = 55
If you have this series: 1,2,3,4,5,6,7,8The 8th term is 8 and the n-th term is n.But if you have this series: 2,4,6,8,10,12,14,16The 8th term is 16 and the n-th term is 2n
