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 |
