Amber is buying ice cream & cookies for a party. ice cream is $2.50 per carton, & cookies are $2 a package. how much will she spend if she buys 2 cartons of ice cream & 3 packages of cookies? $4.50 $5.00 $6.00 $11.00

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
