Question

What is the next number in this set: 90,30, 36, 12, 18, 6, 12, _

Answer 1

4

Step-by-step explanation:

The rule is: Divide by 3, add 6

90/3 = 30

30 + 6 = 36

36/3 = 12

12 + 6 = 18

18/3 = 6

6 + 6 = 12

Therefore, the next step is to divide by 3 again:

12/3 = 4

4 is the next number in the set.
