This data best fits an exponential model.

The regression equation would be:
y = 8385(1.12)^x (There are online calculators for this)

The y-intercept would be the starting value of the account.

Yes, the correlation coefficient is 0.9983.

If you input 6 into the equation, you will get a value of $16,550.
