Series 6, 24, 60, 120, ? What number will come at the place of the ?


Question: What number will come at the place of the question mark (?) in the series 6, 24, 60, 120 ?

Series: 6, 24, 60, 120, ?

Options:

  1. 150
  2. 180
  3. 210
  4. 135

Solution:

This is a number series where a specific pattern exists between the numbers. To solve this, we need to figure out how each number is generated.

The first four numbers in the series are:

  • 6, 24, 60, 120

Now, let’s analyze the pattern by expressing these numbers in a particular mathematical form:

  • 6 can be written as (1 \times 2 \times 3)
  • 24 can be written as (2 \times 3 \times 4)
  • 60 can be written as (3 \times 4 \times 5)
  • 120 can be written as (4 \times 5 \times 6)

Now, we can see that each number follows the form (n(n+1)(n+2)), where (n) starts at 1 and increases by 1 in each step.

For the next number, (n = 5), so:

  • (5 \times 6 \times 7 = 210)

Thus, the next number in the series is 210.

Answer:

The correct answer is: 3. 210
