What's next in this number sequence - 8, 7, 56, 7, 6, 42, 6, x?

Answer 1

Every third number in the sequence is the product of the prior two numbers:

8*7 = 56

7 *6 = 42

6*x

The other pattern is that every three numbers starting at the first drops by one, so going by that, it would be

6*5 = 30

So x would be 5.
