A scientist carbon-dates a piece of fossilized tree trunk that is thought to be over 5000 years old. The scientist determines that the sample contains 65% of the original amount of carbon- 14. the half-life of carbon-14 is 5730 years. Is the reputed age of the tree correct? Explain.

Arithmetic Sequences: the difference between consecutive terms is constant. (adding the same number every time)

With 75 participants, the bike-a-thon will raise a minimum of $3725

Geometric Sequences The ratio between consecutive terms is constant. (multiplying the same number for every number).

Arithmetic Series a series whose terms form an arithmetic sequence. When you know only the 1 st and last term of the sequence, you can use a formula to evaluate the related series quickly.

Explicit formula for the sequence Upper limit, greatest value of n. Lower limit, least value of n.

Use Summation notation to write the series 3+6+9… for 33 terms.

Geometric Series is the expression for the sum of the geometric sequence.
