Insert five numbers between 8 and 26 such that the resulting sequence is an A.P

Answer :

Let A1, A2, A3, A4, A5 be the 5 nos Between 8 And 26


Then, 8, A1, A2, A3, A4, A5, 26 are in AP


We know,


An = a + (n - 1)d


A7 = 26 = 8 + (7 - 1)d


d = 3


Hence,


A1 = a + d = 8 + 3 = 11


A2 = A1 + d = 11 + 3 = 14


A3 = A2 + d = 14 + 3 = 17


A4 = A3 + d = 17 + 3 = 20


A5 = A4 + d = 20 + 3 = 23
