Answer -
Let A1, A2,A3, A4, A5 be the 5 numbers between 8 and26
Then, 8, A1,A2, A3, A4, A5, 26 are in AP
By using the formula,
An = a+ (n – 1)d
An =26, a = 8, n = 7
26 = 8 + (7 – 1)d
26 = 8 + 6d
6d = 26 – 8
6d = 18
d = 18/6
= 3
So,
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
