1*1=1
1*2=2
2*3=6
6*4=24
24*5=120
120*6=720

So, 96 is not correct.

The pattern is *1, *2, *3, *4.

So, the missing term = 24x5 = 120.

Correct series is 0! 1! 2! 3! 4! 5! 6!.

5! is 120 not 96.

Series can be written as 1, 1!, 2!, 3!, 4!, 5!, 6! = 1, 1, 2, 6, 24, 120, 720.

So odd number is 96 in given series.
