Find the common ratio r for the geometric sequence, and use r to find the next 3 terms n 1, 2, 3, 4, 5, 6, 7 f(n) 1,4,16,64

mote1985 [20]

Divide the given terms:

4/1 = 4

16/4 = 4

64/16 = 4

R = 4

The next term is the previous term multiplied by 4.

64 x 4 = 256

256 x 4 = 1024

1024 x 4 = 4096

The next three terms are: 256, 1024, 4096

El jardinero de un parque planta flores siguiendo cierto patrón. En la primera fila planta 4 flores, en la segunda 7 y así suces

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.

One number is 3/8 of another number. The difference of the two numbers is 4.2. What is the lesser number

boyakko [2]

Answer:

2.52.

Step-by-step explanation:

If one number is x then the other = 3x/8.

Also x - 3x / 8 = 4.2

x - 0.375 x = 4.2

0.625x = 4.2

x = 4.2 / 0.625

x = 6.72.

So the lesser number is 6.72 * 0.375 = 2.52.
