Answer 2

TL;DR:

- Arithmetic mean is when you insert terms such that the resulting sequence is in arithmetic progression.

Example: two arithmetic means of 1 and 4 are 2, 3 because 1, 2, 3, 4 are in AP.

- Geometric mean is when you insert terms such that the resulting sequence is in geometric progression.

Example: two geometric means of 1 and 8 are 2, 4 since 1, 2, 4, 8 are in GP.
