Benny's:

2.00 / 4 = $0.50 per sandwich

ABC:

1.50 / 2 = $0.75 per sandwich

Sandwich Hut:

2.00 / 2 = $1.00 per sandwich

Benny's has the best deal

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
