Arithmetic Sequences Using Recursion (VCE SSCE General Mathematics): Flashcards

Starting value + rule for finding next term

$t_0 = a, t_{n+1} = t_n + D$

Starting value (initial term)

Common difference

$t_n = a + nD$

Term number (0, 1, 2, 3...)

Sequence increases

Sequence decreases

$D = -2$

First term of sequence
