17th is 3 ..
17th +18....+36th =72
18th+....+37th=72
72-17th+37th=72
so 17th =37=57th...
similarly 83rd=103rd...
going back....
17th=265th=5th term...
like this i created a table for 1 to 20 n found..
1,5,9,13,17 positions have 3
3,7,11,15,19 positions have 4
4,8,12,16,20 positions hav 9
rest 5 pos have x
actually evry 4th position number is repeated
so 5x+5(3+4+9)=72
x = -8/5
so 10th number or 210th number is -8/5

If you can fill the unforgiving minute
With sixty seconds' worth of distance run,
Yours is the Earth and everything that's in it,
And--which is more--you'll be a Man, my son!
