nevsk [136]

Answer:

a) Para i = 4, hay 13 flores en la fila 4.

b) Para i = 7, hay 22 flores en la fila 7.

c) La fila 11 tiene 34 flores.

Step-by-step explanation:

De acuerdo con el enunciado, cada fila tiene tres flores más que la fila inmediatamente anterior, significando que se puede determinar el número de flores de cada fila mediante una serie aritmética:

n = 4+3\cdot (i-1), i \ge 1 (1)

Donde:

i - Índice de la fila de flores.

n - Número de flores del índice de la fila de flores.

a) Para i = 4, hay 13 flores en la fila 4.

b) Para i = 7, hay 22 flores en la fila 7.

c) Si n = 34, entonces el índice de la fila es:

i=1+\frac{n-4}{3}

i = 11

La fila 11 tiene 34 flores.
