Chapter 10 Additional Review Name: ________________________________ For each sequence, state if it is arithmetic, geometric, or neither. If it is arithmetic find an equation for the 𝑛!! term. If it is geometric find the sum of the first 15 terms. 1. 1, 3, 6, 10, 15, … 2. 40, 43, 46, 49, 52, … 3. −4, 12,−36, 108,−324,…
