Solution

The correct option is B

20, 22, 24, 26, 28………


Initial coins the player has is 20 coins

Net no. of coins he gain after clearing a level = coins gained - coins spent
= 6 - 4
= 2

Coins he has after clearing first level = 20 + 2 = 22

No. of coins after clearing second level = 22 + 2 = 24

No. of coins after clearing third level = 24 + 2 = 26

So, the series of coins after clearing each level is 20, 22, 24, 26, 28………
