The sum of three consecutive odd numbers is one hundred fifty - nine

The first number is equal to 51.The second number is equal to 53.The third number is equal to 55.

x + (x + 2) + (x + 4) = 159

Combine like terms.

3x + 6 = 159

Subtract 6 from both sides.

3x = 153

Divide both sides by 3.

x = 51

51 + 53 + 55 = 159

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
