While sorting some change into piggy banks, Larry put 1 coin in the first piggy bank, 3 coins in the second piggy bank, 9 coins in the third piggy bank, 27 coins in the fourth piggy bank, and 81 coins in the fifth piggy bank. If this pattern continues, how many coins will Larry put in the sixth piggy bank?
