Arithmetic And Geometric Progressions

Muhtasari

Some sequences grow by adding the same amount each time; others grow by multiplying by the same factor. The first are arithmetic progressions, the second are geometric progressions, and together they describe an enormous range of patterns, from stacking chairs to compound interest to a bouncing ball.

In this lesson you will learn the formulas for the nth term and the sum of both kinds of progression, and the elegant sum to infinity of a geometric series when the common ratio is small enough. These compact formulas let you jump straight to the 100th term or the total of hundreds of terms without listing them all.

Malengo

Recognise arithmetic and geometric progressions and understand the difference between them.
Use the formulas for the nth term and the sum of the first n terms, and the sum to infinity of a convergent geometric progression.

Maelezo ya Somo

Sequences and series model anything that grows or accumulates in a regular way: savings with regular deposits, populations, loan repayments, even the total distance of a bouncing ball. Arithmetic and geometric progressions are the two most important patterns, and their sum formulas turn long, tedious additions into a single calculation.
