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
