Question 1138571
<br>
I guess it would be 3469131825, if you are counting whole numbers.<br>
Even if you had presented the problem clearly, it still would have been impossible to know what the next number would be.<br>
In ANY problem like this, where you are asked to find the next number(s) in a sequence, or the missing number(s) in a sequence, it is impossible to know the "right" answer, unless there is specific information telling you what kind of sequence it is.<br>
In other words, given any sequence of numbers, you can put any numbers you want in the missing places and get a valid sequence; and any numbers you choose to put in make an answer to the problem that is equally as valid as some "right" answer.
