Question 22

Select the term that will come next in the following series.
6, 24, 60, 120, ?

Solution

6 = 3 x 2

24 = 4 x 6

60 = 5 x 12

120 = 6 x 20

The relation between 2, 6, 12, 20 is

2 + 4 = 6

6 + 6 = 12

12 + 8 = 20

20 + 10 = 30

$$\therefore\ $$The next number in the series 6, 24, 60, 120 is 7 x 30 = 210

Hence, the correct answer is Option A
