This series can be the list of numbers that are only divisible by itself and 1 ie., prime numbers + '1' So the sequence then is 1,2,3,5,7,11,13,17,19......etc.,
What comes next in this series?
0, 1, 2, 720!, ?
In math, the exclamation mark is a factorial, which is the product of every whole number from 1 to n. For example, five factorial is written 5! = 1x2x3x4x5 = 120. By definition 0! = 1. So 720! = 1x2x3x4x...718x719x720, which is a very large number.
