It would help if you proofread your questions before you posted them.
Are you indicating that all the measures of central tendency = 3 or that there are 3 scores?
"Above" what?
The mean acts as a fulcrum (balance point), so if the two scores add to +6, the third must be -6.
Does that help?
statistics (mean, median, mode): X=3 and the first score is 2 points above and the second score is 4 points above how many points below is the third?
