middle finger..... on 1st count 1 comes on thumb followed by 9 in the second count and 17 in the third count.... it forms an AP with a common difference of 8... 1,9,17,25 and so on... if we solve it
a+(n-1)d=1994
then n-1=1994/8
which will give as a remainder.... so 1992 will be counted on thum and then 1993 on index finger and 1994 on middle finger

Index finger;
bcoz the pattern is thumb=8*n+1; index =8*n or 8*n+2;
middle=8*n-1 or 8*n+3; ring=8*n+4 or 8*n-2; little=8*n+5 or 8*n-3;
