Hello Group 2!
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?

hi
ReplyDeleteits najat is anyone there?
Joanna Kieran Tayo?
its najat and i am totally confused with the question.
ReplyDeleteIthink it would take 9 yearsfor there to be a total of 43 famillies because i see in the pattern it adds by 5 each time.
ReplyDelete3+5=8
8+5=13.
13+5=18.
and the whole pattern would go
3,8,13,18,23,28,33,38,43 etc.
and each number equals one year.
3 famillies=1 year,
8 famillies=2 years,
and 13 famillies=3 years etc.
so just to be clear it would take 9 years.
I found the anwser by finding the difference bettween the numbers that ms lewis gave us and then seeing if it would equal to 43 in the end.
i hope you understand.
with all due respect,
Najat
I think:
ReplyDelete8-3=5
3+5=8
8+5=13
13+5=18
then, i kept adding 5 until i get to 43:
23,28,33,38,43
each number equals to an year:
3 famillies=1 year
8 famillies=2 years
43 famillies=9 years
this is how i found the answer!!
