Question

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

Answer 1

Answer:

3

Step-by-step 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.
