An annuity is a series of payments made at equal intervals. Examples of annuities are regular deposits to a savings account, monthly home mortgage payments, monthly insurance payments and pension payments. Annuities can be classified by the frequency of payment dates. The payments (deposits) may be made weekly, monthly, quarterly, yearly, or at any other regular interval of time. Annuities may be calculated by mathematical functions known as "annuity functions".
An annuity which provides for payments for the remainder of a person's lifetime is a life annuity.
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...

Find the final value of a plan in which payments of $800 are made every 6 months for 3 years, earning 10% interest compounded semi-annually. The first payment is made in 6 months.
My Answer:
R = 800, n = 6 , i = 5%
A = R[(1-i)^n - 1] / i
A = 800(1.05^6 - 1) / 0.05
A = $5441.53
So I...
