*a*_{1} = 2
*a*_{2} = 4
*a*_{3} = 6
Match each term with their term number, *n*. 1 to 2, 2 to 4, 3 to 6 Look at each term number next to its corresponding term. 1 × 2 = 2, 2 × 2 = 4, 3 × 2 = 6 Find a way to relate the term number to each term along the way. {*a*_{n}} = 2*n* Rewrite the final rule using braces in terms of *n*. Braces look like this: { }. |
