Question

The 20th term in a shrinking pattern is in the 500’s and the 30th term is in the 300’s. (1)What might the pattern be? (2)How do you know you are right?

*Justify your thinking with words plz

Answer 1

I believe the pattern is for every term you decrease the number by 20, This would fit in because then the 25th term would be 400 and the 30th term would be 300. This is an assumption but it fits into the problem accordingly
