Geometric sequences (with common ratio not equal to −1, 1 or 0) show exponential growth or exponential decay, as opposed to the linear growth (or decline) of an arithmetic progression such as 4, 15, 26, 37, 48, … (with common difference 11).
As progresión xeométricas (con razón diferente a −1, 1 ou 0) amosan crecemento o decrecemento exponencial, en oposición ao crecemento ou decrecemento linear dunha progresión aritmética como 4, 15, 26, 37, 48, … (con diferencia 11).
