Can you see any relationship in the series of numbers below?

**Find out how the numbers are related and then find What comes next in the sequence?**

** 6, 15, 105, 5460, ??**

If you are lazy and do not want to calculate you can just leave the formula for the next number.

So first try to find a formula to get the next number in the sequence.

**Answer:**

The series follows the following logic;

The formula that represent the numbers are as follows;

**[n(n-1)]/2 = next number**

(6 x 5)/2 = 30/2 = 15

(15 x 14)/2 = 210/2 = 105

(105 x 104)/2 = 10940/2 = 5460

Therefore next number will be;

(5460 x 5459)/2 = 29806140/2 = 1,49,03,070

**Answer = 1,49,03,070**
