Describe the pattern of the number sequence 1, 9, 17, 25, 33, ... by using algebraic expressions

8n - 7

Step-by-step explanation:

8n - 7

8 (1) - 7 = 1

8 (2) - 7 = 9

8 (3) - 7 = 17

8 (4) - 7 = 25

8 (5) - 7 = 33

8n + 1, where n is a whole number greater than or equal to 0.

Step-by-step explanation:

Every number on this list is one more than a multiple of 8, so if n is a whole number great than or equal to 0, the expression 8n describes every multiple of 8, and 8n + 1 describes every number one more than a multiple of 8.
