Answer:

563

Explanation:

This is an arithmetic sequence since there is a common difference between each term. In this case, adding to the previous term in the sequence gives the next term. In other words, .

Formula;

L = a + (n - 1)*d

Givens

n = 70

a = 11

d = 8

Solution;

t = 11 + (70 - 1)*8

t = 11 + 69*8

t = 11+ 552

t = 563
