Math Problem Statement

Here is a geometric sequence. Find the missing terms. 3, __, 6, __, 12, __, 24

Solution

You have provided a sequence from a geometric progression: 3, 6, 12, 24. To find the missing terms, we can observe the common ratio between consecutive terms.

  1. Common Ratio Calculation:
    • From 3 to 6: 63=2\frac{6}{3} = 2
    • From 6 to 12: 126=2\frac{12}{6} = 2
    • From 12 to 24: 2412=2\frac{24}{12} = 2

The common ratio (r) is 2.

  1. Finding the Next Term:
    • The next term after 24 would be 24×2=4824 \times 2 = 48.

Thus, the next term in this sequence is 48.

Would you like more details on this or have any other questions? Here are some related questions to consider:

  1. What is the formula for the nth term of a geometric sequence?
  2. How do you find the sum of the first n terms of a geometric sequence?
  3. Can a geometric sequence have a common ratio that is a fraction?
  4. What happens if the common ratio of a geometric sequence is negative?
  5. How can you use the geometric sequence formula to solve real-world problems?

Tip: When working with sequences, always check if the pattern (either by multiplication or division) is consistent across all terms to correctly identify the type of sequence.
