In 1998, the number of newly reported cases of tuberculosis (TB) was about 21,210 and decreased by about 4.73% each year from 1998 to 2002. Write an exponential decay model giving the number of newly reported cases of TB y (in thousands),t years after 1998. All I know how to do is A = 21,210 D:

29.5977692753

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

3 is greater then both of those numbers
