Bellwork gave students a chance to write Explicit and Recursive Formulas for Arithmetic and Geometric Sequences as well as sequences that are neither.

We discussed examples of how to find the first few terms of a sequence given either the Explicit or Recursive Formulas.

Hwk #4 is due tomorrow, Tuesday, September 10, 2019  SAS2 – Topic 1 Exploring – questions 2 and 8.

The remainder of the period we began discussing Arithmetic Series.  Students answered SAS2 Exploring: “Arithmetic Sequences and Series”, questions 9 and 10 in class.  We discussed a short cut method (formula) for finding the sum of the terms in an Arithmetic Series such as the sum of the first 100 Natural Numbers.
