On Sunday night the tank contained 300 gallons, on Monday night it contained 330 gallons, on Tuesday night it contained 390 gallons, and on Wednesday night it contained 510 gallons of water. If this pattern continues, on what day of the week will the tank overflow?

300 + 30 = 330
Tuesday
(330 + 60) = 390
Wednesday
