The range is the difference between the largest and the smallest members of the row.

1/34-1/66=8/561

Far more interesting to find the sum of the row!

I guess the sum is 33/(product of numbers from 34 to 66)

No. 33/(66!/33!) is a VERY small number. Since you are adding together a bunch of positive numbers, then answer must be at least as least as the smallest one.

Sn = 1/34 + 1/35 + .... + 1/66 =

810596235079202952514867757 / 1182266884102822267511361600

= ~.6856

There is no easy formula for this.
