Answer:

See below

Explanation:

For every odd place, the first one, the third one, and so on, the rule to increase each number by 2 then 3 then 5. This is because every even numbered digit, shows how much to increase the other digits by, minus one at the beginning, no change in the middle, and plus one at the end.

I'm always happy to help :)
