You have been studying linear and nonlinear functions. Among the nonlinear functions are quadratic functions. A quadratic function has a squared
variable (x) in its equation. The graph of a quadratic function is a U-shaped
curve called a parabola.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
