What’s on the Sequences and Series poster
A 4-row table: Arithmetic · Geometric.
Arithmetic sequences add a constant. Geometric sequences multiply by one.
- Pattern — add d — multiply by r
- nth term — a₁ + (n−1)d — a₁ · rⁿ⁻¹
- Test — constant difference — constant ratio
- Graph — straight line — curve
An infinite geometric series converges only when |r| < 1. Then the sum is a₁/(1 − r).

- Who is the Sequences and Series poster for?
- Sequences and Series is filed under 10th Grade (ages 15–16), so it matches what that year asks a child to remember. It is equally useful to an older student revisiting math, and to the parent or teacher answering the question at the kitchen table.
- When should you use the Sequences and Series poster?
- Check the differences and the ratios. Whichever is constant names the sequence. A wall chart earns its place by being glanceable from where the work is happening, so Sequences and Series belongs on the wall where that math work actually happens, within glancing distance, rather than filed away.
- What other posters go with Sequences and Series?
- Completing the Square, Complex Numbers and Inverse Functions sit alongside Sequences and Series in the 10th Grade set. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Completing the SquareComplex NumbersInverse Functions
- Is the Sequences and Series poster free to download and print?
- Yes. Sequences and Series downloads as a free PDF with no account, no email and no watermark, like everything else in the 10th Grade set. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Sequences and Series poster print at?
- Sequences and Series is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Sequences and Series loses nothing.Printing guide
