1. Complete Question :- Kane is training for a marathon. He starts by running 3 miles during every training session each week plans to increase the distance of his runs by 1/4 mile. Let w be the number of weeks. Write and expression to show the distance kane runs in a training session after w weeks ?

   Solution :–

   → first week kane runs = a = 3 miles .

   → increased speed every week = d = (1/4) mile .

   → Total week = n = w .

   we know that,

   • Tn = a + (n – 1)d where
   • a = first term .
   • n = total terms .
   • d = common difference .

   so,

   → Tw = a + (w – 1)d

   → Tw = 3 + (w – 1)(1/4)

   → Tw = 3 + (w/4) – (1/4)

   → Tw = (3 * 4 + w – 1)/4

   → Tw = (12 + w – 1) / 4

   → Tw = (11 + w)/4 (Ans.)
