16. Alice writes down three prime numbers that are all less than 100. She only uses the digits 1, 2, 3, 4 and 5, in fact she uses each digit exactly once.
Which of the following prime numbers did she definitely write down?
(A) 2 (B) 5 (C) 31 (D) 41 (E) 53

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

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
