Can anyhow help me with this question:

1, 2, 4, P, 48, 240, Q

What is P and Q?

The answer is P is 26 and Q is 280.

I don't know how to get P is 26 and Q is 280.

Can anyone tell me how to get the number pattern?

Thanks a million!

I only got P=12 & Q = 1440. Not sure how they got 26 & 280.

4 x 3 = 12, 12 x4 = 48, 48 x 5 = 240 and so on. Can you check whether the answers you have got is correct.

It's a number pattern question. My workings are as follows: 1x2=2, 2x2=4, 4x3=12=P, 12x4=48, 48x5=240, 240x6=1440=Q.
