5. Formulating the rule in finding
the next term in a sequence
(M5AL - IIIf – 6)

6. A sequence is an ordered list of numbers.
Each number in the sequence is called a
term. The three dots (…) mean to continue
forward in the pattern. To fill in the missing
numbers or symbols in each sequence,
we need to find out the rule or pattern
for generating the next term.
SEQUENCE

7. A sequence is a list of numbers or objects
in a defined or logical order. Patterns and
repetitive sequences can be found in
nature, shapes, events, sets of numbers
and anywhere.
SEQUENCE

You simply need to analyze the given terms
and identify the rule for generating the next
term in the sequence.
