Answer:
A.
Step-by-step explanation:
Given,
The initial sprinting of Freya = 200 yards,
Also, She gradually increases her distance by 5 yards per day,
So, in second day her sprinting = 200 + 5 = 205 yards,
In third day = 205 + 5 = 210 yards,
In fourth day = 210 + 5 = 215 yards,
...................., so on,.....
Hence, the sequence that shows the given situation,
200, 205, 210, 215, .........
Which is an A.P.
That having first term, a = 200,
Common difference, d = 5,
Thus, the explicit formula for the given situation is,
Option A is correct.
