### Mary reality series project

1. 1. Math Studies Reality Series Project: Geometric Sequences and Arithmetic Series By: Maria Alejandra Aparicio
2. 2. Geometric Sequences <ul><li>Geometric sequences and the real world: Fianance </li></ul><ul><li>We use the following equation: </li></ul><ul><li>an=a1 * r n-1 </li></ul><ul><li>an: last term </li></ul><ul><li>a1: first term </li></ul><ul><li>r: common ratio </li></ul><ul><li>n: position </li></ul>
3. 3. Geometric Sequence Question <ul><li>So let’s say you put in \$100,000 in your bank account when you are 20. It gains a 3.7% interest annually. </li></ul><ul><li>How much money will you have in 1, 2, or 3 years? </li></ul><ul><li>If you could live a lot longer than the average human how much would your account have after 467 years? </li></ul>
4. 4. The Math
5. 5. The Math 45 years
6. 6. The Math 467 years!
7. 7. Arithmetic Series and the Guinness Book of World Records <ul><li>Brenden Adams is 16 years old and holds the record for being the tallest living teenager. </li></ul><ul><li>Brenden’s height is at 2.3 m or 230 cm which by dividing his height by his years we can assume he grew 14.3cm each year. </li></ul><ul><li>If this pattern keeps going how tall will he be when he’s 18? What about when he’s 40 or 59 years old? </li></ul><ul><li>Using the following formula we can find this out: </li></ul><ul><li>Un= u1 + (n-1)d </li></ul><ul><li>Un: last term n: number of series </li></ul><ul><li>U1: first term d: difference (common difference) </li></ul>
8. 8. Solving for Brenden’s Height
