user: I've been planning my financial future and I've decided to make an initial investment of $10,000, followed by an annual contribution of $1,000. My investment plan will run for 5 years, and I'm expecting an annual return of 5%. However, I'm also aware that inflation can impact the value of my investment, so I've projected an inflation rate that changes year over year: 1% for the first year, 2% for the second, and so on, up to 4% for the last two years. I need to calculate the real value of my investment after accounting for these inflation rates. Can you provide me with the adjusted value of my investment over this 5-year period?
