Answer by JKismyhusbandbae: So to find the pattern we can subtract 49 and 42 to get 7 which should be our pattern to double check add 49 plus 7 to get 56 so 56 plus 7 equals 63.
1. Betty collected 42 petition signatures on the first day, 49 on the second day, and 56 on the third day. If this pattern continues, how many signatures will she collect on the fourth day? Explain how you obtained your answer.
The pattern is getting 7 more signatures everyday.
56 + 7 = 63
I found this answer by finding the rule and adding it to the third day to get the total amount of signatures for the fourth day.
