The correct sequence to show exponential growth where the population of 120 is doubling every day is:
120, 240, 480, 960, 1,920, . . .
However, this option is not listed in the responses you provided. The closest response available that follows some form of exponential growth is:
120, 240, 480 . . .
This is the correct choice as it reflects the doubling behavior correctly for the first three terms.
