how much is needed for extention to 22,23,24?

Expand to 22 cost 700,000 coins or 40 gems (also requires 45 neighbors).

I don't have the information for the other ones at the moment.

i guess every level is 100,000 coins and 5 neighbors increment since my last level 21 was 600,000 coins and 40 neighbors.
