Math Problem Statement
14,10,28,17,49,?
Solution
The given sequence is . Let's analyze the pattern step by step to find the next term.
-
From 14 to 10: Subtract 4.
-
From 10 to 28: Add 18.
-
From 28 to 17: Subtract 11.
-
From 17 to 49: Add 32.
Looking at this pattern:
- The subtraction step seems to decrease by 7 each time (-4, -11).
- The addition step seems to increase by 14 each time (+18, +32).
If the pattern continues, the next step should involve subtracting 7 more than the previous subtraction, and then adding 14 more than the previous addition.
So:
- The next subtraction should be .
- Subtracting 18 from 49:
Therefore, the next term in the sequence is 31.

Here are 5 related questions:
- Can you identify the general rule or formula for this sequence?
- How would the sequence continue after 31?
- What happens if the pattern of addition and subtraction changes in the sequence?
- How does this sequence compare to an arithmetic sequence?
- What would happen if we introduced multiplication or division into this sequence?
Tip: When analyzing sequences, alternating patterns (e.g., addition/subtraction or multiplication/division) often reveal more complex structures.
