Today I will learn to:Calculate unknown numbers in linear sequences Level 3Challenge Objective:Calculate unknown numbers when there is more than one solution Level 4
Key WordsSequence, Generate, Term, Common, Describe
•All will find unknowns involving adding•Most will find unknowns when
subtracting & multiplying• Some will find solutions when
there is more than one solution
Why use algebra?
How can we write this in an algebraic formula?
