Question

Write an equation that models the sequence 200, 500, 1250, ...

Answer 1

The answer could be 200+500+1250=1950

Answer 2

If you add 300 to 200, you get 500. If you add 450 to 300, you get 750, and 750 + 500 = 1250. So, i'm thinking it could be 200 + 300 = 500, 300 + 450 = 750, 500 + 750 = 1250. Hope this helps you, and best of luck!!!
