The recursive rule that represents the situation where the population of a country triples each year is:
a_n = a_(n-1) * 3
The recursive rule that represents the situation where the population of a country triples each year is:
a
n
=a
(n−1)
⋅3.
In this rule, "a
n
" represents the population at year "n", and "a
(n−1)
" represents the population at the previous year, "n-1". The rule states that to find the population at year "n", you multiply the population at year "n-1" by 3 (since the population triples each year).
By using this recursive rule, you can calculate the population of the country at any given year by applying the rule to the population of the previous year.
