What Is an Arithmetic Sequence?
An arithmetic sequence is a number series where the difference between consecutive numbers remains constant.
Example: 2, 5, 8, 11, 14 … (Common Difference = 3)
What Is an Arithmetic Sequence Calculator?
An arithmetic sequence calculator is an online tool that automatically calculates:
- Common difference (d)
- Nth term (an)
- First term (a1)
- Total number of terms (n)
- Sum of arithmetic series (Sn)
You just enter the values → click calculate → instant result.
Perfect for:
✔ Students
✔ Teachers
✔ Exam aspirants
✔ Competitive exams (SSC, Banking, Railway)
✔ Engineers
✔ Anyone learning mathematics
How to Use the Arithmetic Sequence Calculator (Step-by-Step)
Step 1: Enter the first term (a1)
Step 2: Enter the common difference (d)
Step 3: Enter the number of terms (n)
Step 4: Click “Calculate”
Step 5: Get instant result with steps and explanations
This tool saves time and avoids calculation mistakes.
Arithmetic Sequence Formula (Simplified)
1. Nth Term Formula
an = a1 + (n – 1)d
2. Sum of n Terms
Sn = n/2 × [2a1 + (n – 1)d]
3. Common Difference
d = an – a1 / (n – 1)
Example Calculation (Easy Explanation)
Let the sequence be: 4, 9, 14, 19, 24 …
- a1 = 4
- d = 5
- n = 6
Find the 6th term (a6):
a6 = 4 + (6 – 1) × 5
a6 = 4 + 25 = 29
Find the sum of first 6 terms (S6):
S6 = 6/2 × [2×4 + (6 – 1)×5]
S6 = 3 × [8 + 25] = 99
