Exercise 10 Page 279

Look for a relationship between consecutive terms.

Pattern: Divide by $2$ the previous term.
Next Two Terms: $\frac{1}{2},$ $\frac{1}{4}$

Practice makes perfect

We are given a sequence, want to describe the pattern, and find the next two terms.

8, 4, 2, 1, \dots

As we can notice from the sequence, each term is equal to the previous term divided by

2 .

We can describe the pattern as divide by

2

the previous term.

8 ⟶ \div 2 4 ⟶ \div 2 2 ⟶ \div 2 1 ⟶ \div 2 \dots

The next two terms can be found by extending this pattern.

8 ⟶ \div 2 4 ⟶ \div 2 2 ⟶ \div 2 1 ⟶ \div 2 \frac{1}{2} ⟶ \div 2 \frac{1}{4}
