2 - 3 - 6 - 7 - 8 - 14 - 15 - 30 which does not belong?

Answer 1

The 8 does not belong. The sequence of numbers alternates adding 1 to the previous number and doubling the previous number.

2

3 = 2 + 1 (adds 1 to previous number)

6 = 3 x 2 (doubles previous number)

7 = 6 + 1 (adds 1 to previous number)

14 = 7 x 2 (doubles previous number)

15 = 14 + 1 (adds 1 to previous number)

30 = 15 x 2 (doubles previous number)

Answer 2

The number 14 does not belong in the sequence because it is the only even number in the series. The pattern in the sequence is that each number is multiplied by either 1.5 or 2 to get the next number: 2 x 1.5 = 3, 3 x 2 = 6, 6 x 1.5 = 9, 9 x 1.5 = 13.5, 13.5 x 2 = 27, 27 x 1.5 = 40.5. So, the next number in the sequence should be 40.5, making 14 the outlier.
