An Introduction to Arithmetic Sequences (VCE SSCE General Mathematics): Flashcards

Pattern where same fixed amount is added/subtracted each time

$D$

$D = ext{any term} - ext{previous term}$

Increasing (ascending) sequence

Decreasing (descending) sequence

Check if difference between consecutive terms is constant

Points lie along a straight line

Positive slope (upward/rising line)

Negative slope (downward/falling line)

Add common difference $D$ to last known term
