Exercise 14 Page 279

Look for a relationship between consecutive terms.

Pattern: Multiply by 10 the previous term.
Next Two Terms: 20 000, 200 000

Practice makes perfect
We are given a sequence, want to describe the pattern, and find the next two terms. 2, 20, 200, 2000,...

As we can notice from the sequence, each term is equal to the previous term times 10. We can describe the pattern as multiply by 10 the previous term. 2* 10 →20* 10 →200* 10 →2000* 10 →... The next two terms can be found by extending this pattern. 2* 10 →20* 10 →200* 10 →2000* 10 → 20 000* 10 → 200 000
