Stop Memorizing Sequences and Series Formulas
Watch the Program Demo (6:34)
See all 6 problem types solved in under 7 minutes.
This TI-84 Plus CE program solves arithmetic sequences, geometric sequences, arithmetic series, geometric series, infinite geometric series, and recursive sequences—including Fibonacci types—instantly and accurately.
The Sequences & Series Problem:
Most Algebra 2 and Precalculus students struggle with sequences and series because they:
Can't keep all the formulas straight (An vs Sn vs Gn)
Make arithmetic mistakes with long calculations
Forget which formula variation to use
Struggle with recursive sequences that require iteration
Waste time on homework that should be straightforward
This program eliminates all of those problems.
🎯 What This Program Does:
Arithmetic Sequences
✅ Find any term (An) given A1, d, and n ✅ Find first term (A1) from other values ✅ Calculate common difference (d) ✅ Solve for term number (n)
Geometric Sequences
✅ Find any term (Gn) given G1, r, and n ✅ Find first term (G1) from other values ✅ Calculate common ratio (r) ✅ Solve for term number (n) using logarithms
Arithmetic Series
✅ Sum using Sn = n/2(A1+An) ✅ Sum using Sn = n/2(2A1+(n-1)d) ✅ Solve for any variable in the formulas ✅ Find number of terms from sum
Geometric Series
✅ Calculate finite geometric sums ✅ Solve for G1, r, or n from sum ✅ Handle both |r| < 1 and |r| > 1 cases
Infinite Geometric Series
✅ Automatic convergence testing (|r| < 1) ✅ Calculate sum to infinity ✅ Solve for G1 or r from infinite sum ✅ Error messages for divergent series
Recursive Sequences
✅ Linear recursion: An = C·A(n-1) + d ✅ Fibonacci-type: An = A(n-1) + A(n-2) ✅ Built-in help with 8 common recursive types ✅ Examples for geometric, arithmetic, quadratic, alternating, and compound recursion
Perfect For:
Algebra 2 students learning sequences and series
Precalculus students needing recursive sequence help
AP Precalculus students (recursion is heavily tested)
SAT/ACT prep (sequences appear regularly)
Anyone who wants to check homework answers quickly
