The front row in a movie theatre has 23 seats. If you were asked to sit in the seat that occupied the median position, in which seat would you have to sit?

12

Step-by-step explanation:

The median is the one in the middle.  For an odd number of seats, average the first and last seat numbers.

(1 + 23) / 2 = 24 / 2 = 12.  That means there will be 11 people on your left and 11 people on your right.

For an even number of seats, the same method doesn't work as well!  If there are 14 seats, for example,  (1 + 14) / 2 = 15 / 2 = 7.5,  and if you sit in "seat" 7 and a half, it will be awkward!
