Answer

Makes sense.

Work Step by Step

If we look at the formulae for the nth term we can clearly see the difference, thus the statement makes sense. Geometric: $a_n=a_1\cdot r^{n-1}$, where $a_1$ is the first term and $r$ is the common ratio. Arithmetic: $a_n=a_1+(n-1)d$, where $a_1$ is the first term and $d$ is the common difference.
