Given that 10 A.M's between 3,10.
Let 10 arithemetic means be 3, a1, a2, a3, a4, a5, a6, a7, a8, a9, a10, 10
According to the question it is an arithmetic progression.
t12 = 10
a + 11d = 10
3 + 11d = 10
d = 7/11
Hence, a1 = 3 + 7/11 = 40/11
Similarly find the other arithemetic means we get
a2= 47/11, a3 = 54/11, a4 = 61/11, a5 = 68/11, a6 = 75/11, a7 = 82/11, a8 = 89/11, a= 96/11, a10 = 103/11
Find the mean of 10 numbers we get 6.5.
