Question

number of donkeys that Luisa has to retrieve n days after she received her gift isdefined by the arithmetic sequence f(n) = 3500 - 48(n - 1). How many donkeys doesLuisa still have to retrieve 23 days after receiving her gift?

Answer 1

In this case, we are given the following sequence:

f(n) = 3500 - 48(n - 1)

Where n is the number of days after she receives her gift, since we are asked to calculate how many donkeys does Luisa still has to retrieve after 23 days she receives her gift, we just have to replace 23 for n into the formula of the sequence to get:

f(23) = 3500 - 48(23 - 1)

f(23) = 3500 - 1056

f(23) = 2444

Then, Luisa still has to retrieve 2444 donkeys.
