Question

An arithmetic sequence has the recursive formula an = an-1 + d. If the common difference between the terms of the sequence is -11, what term follows the term that has the value 11?

Answer 1

`0`

Explanation:

`a_n` is the term that follows `a_(n-1)`

If `a_(n-1) = 11` and the common difference `d=(-11)`

Then `a_n = 11+ (-11) = 0`
