Given the following question:
Rule one: + 3
Rude two: + 9
3, 6, 9, 12, 15
3 + 3 = 6 + 3 = 9
9 + 3 = 12 + 3 = 15
= 15
9, 18, 27, 36, 45
9 + 9 = 18 + 9 = 27
27 + 9 = 36 + 9 = 45
= 45
We are now given..
3, 6, 9, 12, 15
9, 18, 27, 36, 45
They are related because these terms also have a rule, if you mutlply 3, by 3 we get 9, if we multiply 6 by 3 we get 18. The second sequence is three times the corresponding term in the first sequence or the first option.
Your answer is the first option.
