Question

For each sequence, find a formula for the general term, An

Answer 1

Starting with n = 1, the first sequence is given by

(n - 1)/n

since 0 = (1 - 1)/1, and each successive term has a numerator that is 1 less than the denominator.

The second sequence is

1/(3n)

since each denominator is a positive multiple of 3.
