I am trying to add the following payments for rent over 10 year period $132.62, $133.30, $134.85, $137.00, $137.48, $139.42, $139.74, $141.86, $144.78 and $146.14. I need to write down an equation for the above quantity using Summation Notation and don't know how. There are 52 weeks in a year and not sure how to show equation x52 using summation notation.

Each dollar amount equals what was paid per week for each year from 2004 to 2013. I need to know how to write down an equation for the above quantity using summation notation. The amount $132.62 was for 2004, $133.30 for 2005 etc. I also don't understand how to show it using summation notation x52 weeks each year.
