Dale used these steps to form a number pattern. 1. The first term is 3. 2. The second term is 5. 3. Each term after the second is the sum of the two terms just before it. The first five terms in Dale's pattern are the following: 3, 5, 8, 13, 21, ... What are the next 3 terms?

• 27, 34, 42

• 29, 37, 45

• 34, 55, 89

• 34, 55, 99

Answer explanation

The next three terms in Dale's number pattern are 29, 37, and 45, as each term is the sum of the two terms before it. Therefore, the correct choice is 29, 37, 45.

Mrs. Johnson asked her 6th-grade students to form a number pattern using these rules. 1) Use the number 1 as the first term. 2) To find any other term, double the previous term and add 2. The first two numbers in the pattern are 1 and 4. What is the 4th number in the pattern?

• 20

• 22

• 44

• 46

Answer explanation

To find the 4th number, double the previous term (4) and add 2: 4*2 + 2 = 10. Then repeat: 10*2 + 2 = 22, 22*2 + 2 = 44. Therefore, the 4th number in the pattern is 44.
