Question

1, 6, 24, 81, 255 solve this problem​

Answer 1

Answer : 120.

I have two methods to solve this :

Method 1 :

1 x 1 = 1

2 x 1 = 2

3 x 2 = 6

4 x 6 = 24

5 x 24 = 120

6 x 120= 720

and so on.

Method 2 :

1 = 1

1 * 2 = 2

1 * 2 * 3 = 6

1 * 2 * 3 * 4 = 24

1 * 2 * 3 * 4 * 5 = 120

1 * 2 * 3 * 4 * 5 * 6 = 720

1 * 2 * 3 * 4 * 5 * 6 * 7 = 5040

Although both methods are same as you see the pattern…

hope it helps
