So, unless you've been living under a rock, you should know the jackpot for the powerball is at 1.5 billion dollars. I was looking up the distribution of annuity payments and the website said that the payments are not equally distributed. They are incremented by 5% each year. Like the nerd I am, I tried figuring out the math but didn't know where to start. I know that 1.5 billion / 30 payments = 50 million a year (before taxes) How would you go about figuring out 30 payments equating to 1.5 billion but the condition is that each payment is 5% more than the next?
