Question 49

Identify the number that does NOT belong to the following series.

1.5, 2, 3, 6, 18, 108, 1964

Solution

$$1.5\times2 = 3$$

$$2\times3 = 6$$

$$3\times6 = 18$$

$$6\times18 = 108$$

$$18\times108 = 1944$$

So here '1964' is not following the above-given logic. Hence this does not belongs to the series.
