i want someone to help me with this assignment

i want to create my own exercise that includes the following question writen in the description

n You must create ONE scenario (like the cow) that includes all the following: an ordinary annuity, an arithmetic gradient, a geometric gradient, an effective interest rate problem where CP and PP are different, one of the series must be deferred, and from that cashflow problem you must find the NPV the EAA and derive the formula for the IRR (no need for the IRR answer just the formula). That's 8 seperate components for 8 separate grades and 2 points for an interesting and/or entertaining realistic question.
