Two RulesSeries teasers are where you try to complete the sequence of a series of letters, numbers or objects.
There are two rules that need to be followed when doing these series.
12, 6, 3, 10, 5, 16, 8, ?, ?, ?
17, 52, 26, 13, 40, 20, 10, 5, ?, ?, ?
What do these two patterns have in common?
HintThe first rule is about odd numbers and the second rule is about even numbers.
Answer1st pattern is 4, 2, 1
2nd pattern is 16, 8, 4
The rules are:
If odd, multiply by three and add one.
If even, halve the number.
Both the numbers are doomed to a 4,2,1 pattern.
