Question

Given an = 3n-5, what is the common difference?

Answer 1

3

Explanation:

A common difference is found in arithmetic sequences. The simplified formula for arithmetic sequences, which is what is used here, is
`a_(n)=dn-a_(0)`. Where d is the common difference and
`a_(0)` is the zeroth term. So, in the given equation 3 must be the common difference.
