Look at this series: 1, 4, 14, 53,230....... What number should come next?

This series seems to be increasing exponentially. Let's try to find a pattern:

1. 1 * 2 + 2 = 4
2. 4 * 3 + 2 = 14
3. 14 * 4 + 1 = 53
4. 53 * 5 - 5 = 230

So, the pattern seems to be: multiply the current number by the next number in the sequence (starting from 2), then add or subtract a number to get the next number in the series. The number to add or subtract seems to be alternating between 2 and 1, and then -5.

Following this pattern, the next step would be:

230 * 6 - 6 = 1374

So, the next number in the series should be 1374.
