Activity

Task: Investigate the sequence below to find a pattern in the fractions represented by each term.

### The arithmetic approach (show more)

- The student is able to calculate the value of terms and give these as a simplified fraction. The student can find a pattern and use this to predict the next term.

### The procedural algebraic approach (show more)

- The student understands operations on fractions to write each term as a simplified fraction. The student can find a pattern and use this to predict the next term.

### The conceptual algebraic approach (show more)

- The student is able to generalise operations on fractions to write a general term for the sequence.
