Determine an AP whose 3rd term is 16 and when 5th term is subtracted from 7th term, we get 12

Answer»

Let AP have first term a and common difference d.Given: a(3) = 16According to question,a(7) - a(5) = 12a + 6d - a - 4d = 122d = 12d = 6So, a(3) = 16a + 2d = 16a = 16 - 12 = 4a = 4

So, AP is 4, 10, 16, 22.......
