The correct answer is A) 300 yd.

Using the formula, we have 200 + (21-1)(5) = 200+20(5) = 200+100=300

Solution:

we are given that

Freya is training for a track race. She starts by sprinting 200 yards. She gradually increases her distance, adding 5 yards a day for 21 days.

The explicit formula that models this situation is a_n = 200 + (n-1)5

we have been asked to find how far does she sprint on day 21?

Substitute the value of n=21 in the given explicit formula we get

a_{21} = 200 + (21-1)5

Simplify we get

a_{21} = 200 + 20*5

a_{21} = 200 + 100

a_{21} = 300

Hence the correct option is A.

To get -2 from 2, you would multiple by -1.

To get 2 from -2, you also would multiple by -1.

Ad infinitum.

So the common ratio is -1.

Hope this helps.
