Linear Sequences (Junior Cert Mathematics): Flashcards

Set of numbers/shapes/objects following a specific rule

List of numbers following a certain rule

The numbers in a sequence

Constant difference between consecutive terms

Sequence where difference between terms is always the same

Formula to find any term without listing all before it

$T_n$

$T_n = a + (n-1)d$

First term of the sequence

Common difference

Term number (position in sequence)

Set $T_n$ equal to value and solve for $n$
