Sequences: A list of numbers or objects in a special order.     

Position: where a term is located in a sequence        

Term: In Algebra a term is either a single number or variable, or numbers and variables multiplied together. 

Ascending: Arranged from smallest to largest, increasing   

Descending: Arranged from largest to smallest, decreasing

Linear: a straight line

Linear Sequences: A linear sequence goes from one term to the next by always adding (or subtracting) the same value)        

Non-Linear: The difference between terms increases or decreases in different amounts.

Constant: A fixed value.

Command words:   

Describe (a sequence): Use mathematic operations to tell how a sequence change from one term to the next. 

For example: Subtracting 5 each time/ Multiplying the previous term by 4/ Adding the two previous term together for Fibonacci Sequence

Explain (your answer): To provide a reason to support your answer. 

For example: I think Dora is correct because...

Predict: Forecasting the required term in a sequence based on observations/ finding the term-to-term rule.
