  1. Warm up 2. 3.

  2. Questions over HW?

  3. Geometric Sequence A sequence of terms that have a common ratio between them

  4. Explicit Formula Formula used to find the nth term of a sequence

  5. Explicit Formula for Geometric Sequence Where a1 is the first term in the sequence and r is the common ratio

  6. Geometric Sequence Example 1: Find the common ratio r = 2

  7. Geometric Sequence Example 2 : Find the common ratio 256, 64, 16, 4, … r = 1/4

  8. Example 3: Find the common ratio, the explicit formula, and the seventh term. 6, 3, 1.5, 0.75 …

  9. Example 4: Find the common ratio, the explicit formula, and the tenth term. -4, -12, -36, -108 …

  10. Example 5 : The fifth term is 1,792. The common ratio is 4. Write the explicit formula.

  11. Example 6 : During the month of October, a few teachers decided to spread some holiday fun by starting a game of getting “boo”ed. On the first day, 3 teachers were given “boo” bags and directions to “boo” 2 other teachers. If every teacher followed the directions to “boo” 2 teachers with candy and a sign, find the following: a. The explicit formula b. The first 4 terms 3, 6, 12, 24…
