The entire question (including title) is:
What number comes next?
3, 1, 4, 8, 8, 23, 23, 66, 136, 202, 458, 885, ?
Find the number that comes next.
We have been told nothing. This could be anything from mathematical to the number of partridges in a pear tree to what colour socks am I wearing, reducing the problem to mind-reading the OP.
The sequence is not credited, and home-grown efforts often suck!
On other SE sites this question would be closed and deleted without question.
Should we have a set of guidelines as to the minimal requirements for a question so we can refer this level of question to them?
