Arithmetic and Geometric Sequence Calculator

Coded by: Sir Rich

This program provides a simple and effective tool for students, mathematicians, or anyone needing to work with sequences.

What is the Sequence Calculator?

This isn't just another tool that finds the next number in a pattern. The Ultimate Sequence Calculator is a versatile application that can solve for any unknown variable in both arithmetic and geometric sequences. Need to find the common ratio? The first term? The total number of terms? Our calculator has you covered.

It's built with a clean, user-friendly interface that makes complex calculations feel simple.

Features

Dual Modes: Seamlessly switch between Arithmetic and Geometric sequence calculations with a single click.
Solve for Any Variable: The calculator's core strength is its flexibility. You can solve for:
The nth Term ()
The First Term (a)
The Common Difference (d) or Common Ratio (r)
The Number of Terms (n)

How to Use the Calculator: A Simple Guide

Getting your answer takes just four easy steps:

1. Select the Sequence Type: At the top, choose between the "Arithmetic" and "Geometric" tabs. The form will update accordingly.

2. Choose the Variable to Solve For: Use the dropdown menu labeled "Variable to Solve For" to select the unknown you want to find (e.g., "Common Difference (d)").

3. Enter the Known Values: Fill in the input fields for the values you already have. The field for your chosen unknown will be grayed out.

4. Calculate! Click the "Calculate" button. The result will appear at the bottom in a clear, easy-to-read box, telling you exactly what was calculated.

Result Display: The calculated term is shown in a distinct result box at the bottom.
