Outcome: demonstrate an understanding of the relationships that exist between arithmetic operations and the operations used when solving equations

Originators: Dylan, Matthew

An arithmetic sequence is an ordered set of numbers formed according to some pattern or rule

{4,7,10,13,.....} The dots are ellipsis' which means that this sequence is infinite

The formula for an arithmetic sequence is

tn=t1+d(n-1)

t1= the first term in the sequence

d= common difference

n= any term in the sequence

A sequence that has a comon difference is called an arithmetic sequence

{2,4,6,8,...}

V V  V

{2,2, 2,....}   D2= 2

{1,3,5,7,9,11,13,15,...}  tn=2n-1
