Suppose the seven numbers are a,b,c,d,e,f and g The arithmetic mean of all 7 is 10. So the sum of all seven ie a+b+c+d+e+f+g is 10*7 = 70. The arithmetic mean of the fist six a to f is 11. So their sum (a+b+c+d+e+f) is 11*6 = 66. So, g = (a+b+c+d+e+f+g) - (a+b+c+d+e+f) = 70-66 = 4
Call the specified numbers a, b, c, d, e, f, and g and the unknown number x. From the problem statement, (a + b + c + d + e + f + g)/7 = 9 [from the definition of "mean" of a set of numbers]. Also (a + b + c + d + e + f + g + x)/(7 + 1) = 9 - 3 = 6, or x/8 = 6 - [(a + b + c + d + e + f + g)/8], or x = 48 - (a + b + c + d + e + f + g).

The general formula for the number of combinations of r things chosen from n different things is C(n,r) = n!/ r!(n-r)! How many ways can 5 players be chosen from a team of 13? (Where the order you choose the players does not matter). So C(13,5) = 13!/5!(13-5)! Or 1,287

This is pretty much the standard repertoire to learn for any beginning piano student. I learned it and never forgot it.
