Please answer correctly, I'm struggling.

Step-by-step explanation:

2x² + 5x - 3 = 2x² - x + 6x - 3*1

                  =x(2x - 1) + 3(2x - 1)

                 = (2x -1)(x + 3)

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
