Step-by-step explanation:
let a1 = 23, a2, a3, a4, a5, a6, a7 =77
an = a1 + (n - 1)d
77 = 23 + (7 - 1)d
77 = 23 + 6d
77 - 23 = 6d
54 = 6d
9 = d
since d = 9, then
a2 = 23 + 9 =32
a3 = 32 + 9 = 41
a4 = 41 + 9 = 50
a5 = 50 + 9 = 59
a6 = 59 + 9 = 68
Therefore, the five arithmetic means between 23 and 77 are: 23, 32, 41, 50, 59, 68, 77.
