That's the order from least to greatest
The explicit rule is an = a1 + 12 * (n - 1).
From the recursive rule, we can tell that each term is 12 more than the previous term, so we can write a1 + 12 * n.
However, if that's the rule, then when a1 is plugged in, it doesn't work. So, we must do 12 * (n - 1) to make it work.
Therefore, the explicit rule is:
an = a1 + 12 * (n - 1).
There are three groups of people: 25 years old and younger, between 25 to 50, and 50 years old and older. Their fractions must equal to 1 because these three together form the whole.
1 = 1/3 + 2/7 + x
where x is the fraction for people ages 25 to 50 years old
x = 8/21
So, the actual number of people ages 25 to 50 years old is:
84(8/21) = 32 people
