Create a sequence to show exponential growth where the population of 120 is doubling every day.

A. 120, 360, 1,080 . . .
B. 120, 240, 480 . . .
C. 120, 60, 30 . . .
D. 120, 240, 480, 360, 480 . . .

To show exponential growth where the population of 120 is doubling every day, we start with 120 and multiply it by 2 for each subsequent day.

  • Day 0: 120
  • Day 1: 120 * 2 = 240
  • Day 2: 240 * 2 = 480
  • Day 3: 480 * 2 = 960
  • Day 4: 960 * 2 = 1920
  • and so on.

The correct sequence that represents this exponential growth starting from 120 and doubling each day is:

B. 120, 240, 480, ...

So, option B is the correct answer.
