Answer: r = 1/2
Next three terms = 1/2, 1/4 and 1/8.
Explanation:
This is a geometric progression and the common ratio will be calculated as the second term divided by the first term. This will be:
= 4/8.
= 1/2
The next three terms will then be:
1 × 1/2 = 1/2
1/2 × 1/2 = 1/4
1/4 × 1/2 = 1/8
Therefore, the next three terms are 1/2, 1/4 and 1/8.
