Sequences & Series Solver (TI-84 Plus CE)
🔢 Arithmetic, Geometric, Infinite, and Recursive — Solve for Any Variable
Six sequence and series problem types, solved for any variable. SEQNSER1 covers arithmetic sequences, geometric sequences, arithmetic series, geometric series, infinite geometric series (with convergence testing), and recursive sequences including Fibonacci-type. Enter what you know — it finds what you need. Built-in help menus show formulas and worked examples right on the calculator.
What's Included
| File Name | Type | What It Does |
|---|---|---|
| SEQNSER1 | Solver Program | Full solver for six sequence and series types: arithmetic sequences (any variable — An, A1, d, n), geometric sequences (any variable — Gn, G1, r, n via logarithms), arithmetic series (both sum formulas, any variable), geometric series (finite, any variable), infinite geometric series (convergence check, sum to infinity, solve for G1 or r), and recursive sequences (linear, Fibonacci-type, with 8 built-in recursive type examples). Includes built-in help menus with formulas and examples. |
What SEQNSER1 covers:
- ✅ Arithmetic sequences — solve for An, A1, d, or n
- ✅ Geometric sequences — solve for Gn, G1, r, or n (via logarithms)
- ✅ Arithmetic series — both sum formulas, solve for any variable
- ✅ Geometric series — finite sums, solve for G1, r, or n
- ✅ Infinite geometric series — convergence test, sum to infinity, solve for G1 or r
- ✅ Recursive sequences — linear and Fibonacci-type, with 8 built-in examples
- ✅ Built-in help menus with formulas and worked examples
Best for: Algebra 2 and Precalculus students, AP Precalculus students (recursive sequences are heavily tested), and SAT/ACT prep where sequences appear regularly.
Compatible Calculators
✅ TI-84 Plus CE
✅ TI-84 Plus CE Python
✖ Not for TI-83, TI-Nspire, or Casio calculators.
