Dave started his coin collection with 25 coins. the first wee he added 2 coins, the next week he added 4 coins, and the third wee he added 6 coins. If Dave continues adding coins in the same way, how many coins will he have in his collection after one year (52 weeks)?
My answer is 2781, is this correct?

That's what I get, too.
