Incredibly Hard MALTHUS Problem Help Needed

I am here once again because I have no idea what I am doing. I am forced into taking this math class to graduate and we have this assignment which I can't figure out. I would be forever grateful for any help possible. The question is stated:

Using Malthus's sequence for unchecked population increase, what would the world's population be in 1900 and in 2000? First write the terms of the sequence. The T(zero) term, which is 1, represents the pop. in the year 1800. So under 1, write 1800 and the worlds population in 1800. Under the rest of the terms in the sequence write the appropriate years and the corresponding populations according to Malthus's sequence. Find the terms in the sequence corresponding to the years 1900 and 2000. You should have the unchecked population numbers for those years.

Then it says "If there was sufficient food for all the people in 1800, how many people would this sequence indicate enough food for in 1900 and in 2000? Use the sequence from the above problem and procedure . The T(zero) term which is 1, represents both the population in 1800 and the food population, since we are assuming enough food for the entire world population at that time.

the last part: "Does this sequence indicate enough food for the number you found above for the year 2000 World Population?"

Oh lord....shoot me now.
