10 Fingers and (10) Toes on the Human Body
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
