Tanya runs a catering business. Based on her records, her weekly profit can be approximated by the function LaTeX: f\left(x\right)=2x^2-44x-150f ( x ) = 2 x 2 − 44 x − 150, where LaTeX: xxis the number of meals she caters. If LaTeX: f(x)f ( x ) is negative, it means that the business has lost money.

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
