The binomials shown below will be multiplied to produce a quadratic trinomial.
(x + p)(x + q)
which part of the trinomial will equal the sum of p and q?
a. the constant term
b. the coefficient of the x-term
c. the degree
d. the coefficient of the x2-term

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
