14 NUMBERS •^ SEQUENCES AND PATTERNSSequences

A sequence is a series of numbers, which we call terms, listed in
a special order. A sequence always follows a set pattern, or rule,
which means we can work out other terms in the sequence.+2 +2 +
A sequence is a set
of numbers, called
terms, that follow a set
pattern, called a rule.We can see that each
number is two more than
the one before. So, the rule for
this sequence is “add two to
each term to find the next term.”Look at this row of houses.
The numbers on the doors
are 1, 3, 5, and 7. Can we find
a pattern in this series?If we use this rule, we can
work out that the next terms
are 9 and 11. So, our sequence
is: 1, 3, 5, 7, 9, 11, ... The dots
show that the sequence
carries on.The rule for this sequence is
“add two to the previous term”(^135)

Each number in a sequence is called a term
