How to Use the Sequence Limit Calculator

Using the Sequence Limit Calculator is simple. Follow these step-by-step instructions:

Step 1: Enter the Sequence Formula

  • Locate the Sequence Formula input field.
  • Type your formula using nnn as the variable.
  • Examples of valid formulas:
    • 1/n
    • n/(n+1)
    • (2^n)/n!
  • Note: Use ^ for exponents and e for Euler’s number.

Step 2: Optional – Enter Number of Terms to Preview

  • You can enter the number of terms you want to preview.
  • If left blank, the tool defaults to 10 terms.

Step 3: Calculate the Limit

  • Click the Calculate Limit button.
  • A progress bar will appear, showing the calculation process.
  • Once complete, the results display the calculated limit and, if requested, the preview of terms.

Step 4: Copy or Share Results

  • Use the Copy Results button to save the results to your clipboard.
  • Use the Share Results button to share via social media or other platforms.

Step 5: Reset if Needed

  • Click the Reset button to clear inputs and start over.

Practical Example

Suppose you want to calculate the limit of the sequence: an=nn+1a_n = \frac{n}{n+1}an​=n+1n​

Steps Using the Calculator:

  1. Enter n/(n+1) in the sequence formula field.
  2. Set the preview to 10 terms (optional).
  3. Click Calculate Limit.

Output:

  • Calculated Limit: 1.00000
  • Preview of Terms: 0.50000, 0.66667, 0.75000, 0.80000, 0.83333, 0.85714, 0.87500, 0.88889, 0.90000, 0.90909

This shows that as nnn increases, the sequence approaches 1.
