What comes next in the sequence and why ? : 1 8 27 125 343


The next number in the sequence is **729**.

Here's why: 

The sequence represents the cubes of consecutive integers, but starting from 1 and skipping 4.

- \( 1^3 = 1 \)
- \( 2^3 = 8 \)
- \( 3^3 = 27 \)
- \( 5^3 = 125 \)
- \( 7^3 = 343 \)

The next integer to cube is 9:
- \( 9^3 = 729 \)

Thus, the next number is 729.

Here are 5 related questions to expand your understanding:
1. What are the cubes of all the numbers from 1 to 10?
2. Can you identify a pattern in the gaps between consecutive terms in the sequence?
3. How does this sequence differ from a standard consecutive cube sequence?
4. What would the sequence look like if it skipped even more numbers, say every other prime?
5. Can you describe a method for quickly recognizing a cube number?

**Tip**: Recognizing patterns in sequences often comes down to checking for basic mathematical operations like powers, multiplication, or primes!
