Imagine that you have five blue socks and five brown socks in a drawer that are not paired up. how many socks must you take out from the drawer (without looking) to be sure of getting a pair of the same color? question 5 options:

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
