Write an equation for each of the following sequences. Homework Help ✎

  1. Going from left to right, how much do the terms decrease?

    Each term is 6 less than the preceding one. This sequence is arithmetic.

  2. Is this geometric or arithmetic?

    This is geometric because there is a common ratio (multiplier) between the increasing terms.
