Recurrence Relations (Leaving Cert Applied Maths): Flashcards

Shows how each term relates to the previous term

Depends on previous term, not position number

Often uses 'u' instead of 'T'

Term equals 3 times the previous term

Term equals previous term minus 4

Term equals half previous term minus 3

$144, 36, 9, \frac{9}{4}$

$r = \frac{1}{4}$

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

$192$

Must calculate all previous terms to find a specific term
