Question

One number doesn't match this factorial series: 2, 6, 24, 120, 720, 1000

• A. 6
• B. 24
• C. 1000
• D. 120

Answer 1

Answer:

C. 1000

The series follows factorials:

• (2 = 2!)

• (6 = 3!)

• (24 = 4!)

• (120 = 5!)

• (720 = 6!)

The next term should be:

7! = 5040

But the series has 1000 instead.

So, the number that does not match is 1000.
