Hello Group 5!
Here's the problem again. Post your ideas as comments here!
The famous Lewis School of Mathematics is building a new section as more families move into the fabulous city of Lewistown. The following numbers of families have moved into Lewistown over the past 4 years: 3 more families than the first year, then 8 more families the following year, then 13 more families the next year, and 18 more families the past year. If this pattern continues, in how many more years will a total of 43 families have moved into town?
