Question

six arithmetic means between 7 and 77

Answer 1

we can look at this from the standpoint that we know the 1st and 8th term of an aritmetic sequence

Answer 2

an = a1 + d(n-1)

a1 = 7; a8 = 77

the 6 values we want are a2,a3,a4,a5,a6,a7

Answer 3

another way is to simply find the range is divide it by 1 more than the number of means your looking for; this gives you a value to keep adding from the smaller number to determine the next 6 values

Answer 4

... or rather next "n" values
