Apply the algebra tiles to find (5x2 + x + 7) + (6x + 4)

see explanation

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

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
