Andrew is a naturalist who's been worried about a deer species. He's been tracking the number of Birth's each year;
Year 1: 4304
Year 2: 2152
Year 3: 1076
Year 4: 538

Predict the number of births in year 5.

I don't even know why I'm having trouble with this, but I am. Help please?

Each year, the number of births is half that of the previous year. Thus, we can predict that in year 5 we'd see 538/2 = 269 births.
