Revision (Grade 11 NSC Matric Mathematics): Flashcards

Sequence with constant difference between consecutive terms

$d$

$d = T_2 - T_1$ (later term minus earlier term)

General term or nth term of a sequence

$T_n = a + (n-1)d$ where $a$ = first term, $d$ = common diff

Increases

Decreases

Straight line

Formula (with $n$) to calculate any term in the pattern

Positive integers only
