Math Problem Statement
Solution
The problem presented in the image asks to "trouver le nombre qui complète logiquement la série" (find the number that logically completes the series) with the sequence:
This is an arithmetic sequence, where each number increases by 5.
Following the same pattern, the next number would be:
So, the correct number to complete the sequence is 28.
Would you like more details on arithmetic sequences or to explore related concepts?
Here are 5 questions to expand on this:
- What is the general formula for an arithmetic sequence?
- How do you find the common difference in a sequence?
- What other types of sequences (e.g., geometric) can be used in problems like this?
- How can arithmetic sequences be applied in real-world scenarios?
- Can arithmetic sequences ever be decreasing?
Tip: In arithmetic sequences, the common difference between consecutive terms is always constant.
