Question

Examples of Arithmetic Progressions in Nature

Answer 1

Growth often includes arithmetic progressions in one way or another.
For example, if you measure the distances of footprints of animals or people along a track, those distances will be in an arithmetic progression. Sunflowers, snails, and lots of other things show geometric progressions rather than arithmetic ones.

Answer 2

A car going in uniform speed, colonies having home in same distance, etc.
