To fill in the response area, we need to identify the multiplicative relationship between consecutive terms in the pattern you are describing. If each term in the sequence is a consistent multiple of the previous term, you would need to know what that multiple is.
For example, if the pattern were doubling (e.g., 1, 2, 4, 8, ...), you would say "2" because each term is 2 times as great as the term to its left.
Please provide the specific terms in the pattern you are working with, and I can give you the exact relationship to fill in the response area.
