The formula that is presented
in the YouTube video Application of arithmetic series in real life
(hosted by mattam66) was derived from looking at many examples of
sequences. If a person took the time to write out the solution by
hand they would come up with the very same answer. Make up an
arithmetic sequence problem (find the 10th value) and share with
the discussion board. Choose one classmates' discussion and try
their problem and share the result. The writer then comments on the
solution.
