Infinite Series (Grade 12 NSC Matric Mathematics): Flashcards

Sum of unlimited number of terms in a sequence

Series sum approaches a certain value; has a limit

Series that does not converge; usually tends to infinity

$-1 < r < 1$

$r < -1$ or $r > 1$

$S_{\infty} = \frac{a}{1-r}$ where $-1 < r < 1$

First term of the series

Common ratio of the series

$r^n$ approaches 0

Arithmetic series never converge
