Answer:
(11+w)/4
Explanation:
Let the first term be 3 miles
If he plans to increase the distance of his run by 1/4 mile, then
common difference = 1/4
To get the distance Kane runs in a training session after w weeks , we will use the nth term of an AP
Tw = a+(w-1)d
Tw = 3 + (w-1)(1/4)
Tw = 3 + 1/4 w - 1/4
Tw = 11/4 + 1/4 w
Tw = (11+w)/4
Hence the distance Kane runs in a training session after w weeks is (11+w)/4 weeks
