T4 and D4
D4 was trying to impress everyone at T4's birthday party by giving T4 a math problem. Celebrating 1994, T4's birth year, what is the 1994th digit in the decimal expansion of 1/7 to the right of the decimal point?
Hint
Actually do the math for a bit...Answer
4.Any number not a multiple of 7 will divide out with the pattern 1,4,2,8,5, and 7. 1/7 is simply 0.1428571428571428571428757... Divide 1994 by 6 and get 332 with remainder 2. 4 is the second digit of the six-digit pattern, so it is also the 1994th digit.

Easy for me, but fairly good.
Is probably very easy for some, but for me, I'm sorry I'm no good at these. As I have said before to others, Sorry, not in my data base. Nice job, tho.
i don't usually care to do the math on these but this one i like.
I'm not sure what you meant by a remainder of 2, but I got a remainder of .3 repeating, and so I found the 2nd number out of the 6 since two-sixths also equals one-third.
Thanks for the comments. And just to clarify, my brother's username is not D4MT, it's bobby33, but D4 goes more along the lines of T4.
Tommy you are a turd queen.
