In today’s class, we changed the topic from quadratic related to number list related: sequence and series. This is the basic of sequence and series in algebra. We started with arithmetic sequence and series which has the same difference between any two consecutive terms. Formulas were derived and the meaningful methods that help in solving problems were also introduced, such as arithmetic mean, steps related to the difference.

Here is the homework for sequence and series

P.594, 21.1.1, 21.1.2, 21.1.3

P.601, 21.2.1, 21.2.2, 21.2.3, 21.2.6, and extra 21.2.5
