Yr 1=750, Yr 2 =825, Yr 3 = 900, Yr 4 = 975, Year 5 =1050,

Year 6=1125, Yr 7 = 1200, Yr 8 = 1275, Yr 9 = 1350 and Yr 10 = 1425

Step-by-step explanation:

1st understand the question. Now that you know that you need to calculate a 10% increase beginning with yr 2, find 10% of $750. 10% of $750 = $75. After Yr 1, add $75 to each subsequent yr. My phone doesn't have Stigma Notation sign yet it means: Sigma Notation. Σ This symbol (called Sigma) means "sum up". There are alot of fun combos using this. Provided above are the rent #'s for yrs 6-10. Now that you have the equation and outcome, use Stigma Notation to write them, if you have to.
