Six thirty-fifths. One fifth is 7/35, one seventh is 5/35, so half way between is 6/35.
(3/5) / (6/7) = (3/5) *(7/6) = (3*7)/(5*6) = 21/30 = 7/10
The total of the 6 numbers is 48 (6x8) Adding another number will take the total to 7. So with an average of 10, the total of the 7 numbers will be 70 (7x10) 70 - 48 = 22 which is our seventh number.

Find the generating equation for the sequence and then substitute the values 5, 6 and 7 (respectively) for the counter - which is usually n.
It is: 1/5+3/7 = 22/35
When starting out with two wholes, that makes 2*(7/7) or fourteen sevenths. Three seventh, or 3/7 is then added. Fourteen plus three makes for seventeen sevenths.
It is: 1/7 of 6 = 6/7 or as 0.'857142' recurring decimals
