Geometric progression

In mathematics, a geometric progression, an aw kent as a geometric sequence, is a sequence o nummers whaur ilk term efter the first is foond bi multipleein the previous ane bi a fixed, non-zero nummer cried the common ratio.

Diagram illustratin three basic geometric sequences o the pattern 1(rn−1) up tae 6 iterations deep. The first block is a unit block an the dashed line represents the infinite sum o the sequence, a nummer that it will foriver approach but niver titch: 2, 3/2, an 4/3 respectively.
