# Where did I find these numbers?

I generated this number sequence by following a pattern. Can you determine that pattern?

1
120
10800
345600
3024000
15780000
220752000

Some rounding was used to get these numbers, so you may be slightly off when you calculate them yourself. If you find the pattern, you've found the answer.

Clue 1:

Each number is X*Y, and both X and Y increase following their own pattern.

Clue 2:

It's only a matter of time before someone finds the answer.

• clue 2 is relevant? seems obvious Oct 27, 2016 at 15:04
• Clue 2 is relevant, but all in due time. Oct 27, 2016 at 15:05
• ohhh I get it ... lets see if I'm in time to solve it Oct 27, 2016 at 15:08

These numbers are

1,2,3,4,5,6,7

times

number of seconds in a second, minute, hour, day, week, month, year

where

a month is taken to be about 30.4 days and a year 365 days, and the figure for a month rounded a bit (it isn't e.g. exactly 1/12 of the figure for a year).

• about to post it! too fast , nice +1 Oct 27, 2016 at 15:10
• darn! I was in the middle of typing up my answer and I saw you beat me to it! Well played Oct 27, 2016 at 15:10
