Jill, being very smart, puts $400 per month in her retirement account at the end of each month. This account earns on average 12% annual interest on the amount in her account. The interest is compounded monthly (therefore she earns 1% interest per month). Let An - = be the amount in her account at the end of n months. (Note that A = 400). Give a recurrence relation for An. DO NOT solve this relation. Jill, being very smart, puts $400 per month in her retirement account at the end of each month.
