Question

Hilary is given the pattern 2, 4, 6, 8, 10,... on her test. She has to find the 50th term of the pattern. To do so she needs to describe the pattern either with words, a recursive formula, or an explicit formula. Which would be the best? Make sure you also explain why the forms you do not choose are not good representations.

Answer 1

50 Term =100

Explanation:

Because term to term rule is 2

Therefore 2x50=100

Answer 2

The 50th number would be 100.

Explanation:

The rule is going up by 2. So, 2 times 50 is 100. I hope this helps!
