I need help with the question on the image, thanks.

Q#10 For each of the following sequences: 1. Identify if the sequence is arithmetic, geometric, or quadratic. Explain why. 2. If it is arithmetic or geometric, give an expression for the sum of the first 20 terms in the sequence. Show your work and any formulas used. You do not need to evaluate this expression. If it is quadratic, determine a formula for the i-th term in the sequence and show your work. А. 4, -8, 16, -32, ... В. 9, 12, 18, 27, ...
