WHAT I KNOW

A. Directions: Study the given number patterns. Find the next term. Write the letter of the

correct answer on the space provided before each number.

A B

1. 25, 30, 35, 40, 45, a. 31

• B. 50, because the pattern is adding by 5

2. 11, 22, 33, 44, 55, 66, b. 50

• D. 77, because the pattern is adding by 11

3. 1, 4, 9, 16, 25, 36, c. -3

• E. 49, because the pattern is 3, 5, 7, 9, etc. Or odd numbers.
