How the Geometric Series Calculator Works
Step 1: Enter First Term
Input the first value of the sequence (a).
Step 2: Enter Common Ratio
Input the multiplier (r).
Step 3: Enter Number of Terms
Define how many terms (n) to calculate.
Step 4: Calculate
The tool returns:
- Sum of series
- Last term
- Sequence breakdown
Formula for Geometric Series
Sum of First n Terms:
Sn=a1−r1−rn
Where:
- Sₙ = sum of series
- a = first term
- r = common ratio
- n = number of terms
Example Calculation
Given:
- First term (a) = 2
- Common ratio (r) = 3
- Number of terms (n) = 4
Step 1: Apply formula
S₄ = 2 × (1 − 3⁴) / (1 − 3)
Step 2: Solve powers
3⁴ = 81
Step 3: Final calculation
S₄ = 2 × (1 − 81) / (−2)
S₄ = 2 × (−80) / (−2)
S₄ = 80
