Choose the single logarithmic expression that is equivalent to the one shown. log2 6 + log2 2 − log2 8 options are: a) log2 (2/3) b) log2 1 c) log2 (3/2) d) log2 4

b. astronomers

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
