Answer» nth term of an AP isan = a + (n - 1)d Where,a = first termd = common difference Given, d = 5/4a9 = - 6 Now,-6 = a + 8da = - 6 - 85/4 = - 6 - 10a = - 16 Therefore,25th terma25 = - 16 + 245/4 = - 16 + 6*5 = - 16 + 30 = 14

Answer»

nth term of an AP isan = a + (n - 1)d

Where,a = first termd = common difference

Given, d = 5/4a9 = - 6

Now,-6 = a + 8da = - 6 - 8*5/4 = - 6 - 10a = - 16

Therefore,25th terma25 = - 16 + 24*5/4 = - 16 + 6*5 = - 16 + 30 = 14
