Answer:

The difference is #24-11=13#

Explanation:

#11,12,13,14,15,16,17,18,19,20,21,22,23,24#

There's no real middle number (#17and18# share the middle), so we take the mean of #11and24or 17and18#:

#(11+24)/2=(17+18)/2=17.5#

Answer:

#((11+24))/2 = 35/2 = 17 1/2 = 17.5#

Explanation:

To find a central value, simply average the two values, which means add them together and divide by #2#

#((11+24))/2 = 35/2 = 17 1/2 = 17.5#

This has many applications in maths:

  • Finding the average between two ages, two tests, etc.
  • Finding the midpoint of a line: #M("ave of x's","ave of y's")#
  • Finding the median of an even number of values.
  • Finding the line of symmetry from the #x# intercepts of a parabola
  • Finding a fraction exactly halfway between two given fractions.
  • Finding the midpoint of a class interval in statistics.

It is the same concept every time: Average the two values to find the one exactly midway between them.
