Find a formula for the nth term of the arithmetic sequence
vagabundo [1.1K]

Answer:

11+2n

Step-by-step explanation:

Arithmetic sequence=a+(n-1)d

a=first number

n=nth term

d=difference

a=9

n=?

d=-2

So let's solve

9+(n-1)(-2)

9+(2n+2)

9+2n+2

Collect like terms

9+2+2n

11+2n

So the nth term is 11+2n

El tamaño de cierto cultivo de bacterias se multiplica por 2 cada 30 minutos. Si suponemos que el cultivo tiene inicialmente 256
Oduvanchick [21]

Answer:

La población de bacterias después de tres horas es de 2^{14} bacterias.

Step-by-step explanation:

En este enunciado observamos un caso de progresión geométrica, en donde la población de bacterias se duplica cada treinta minutos, es decir:

\frac{p(n\cdot\Delta t)}{p(0)} = 2^{n} (1)

Donde:

\Delta t - Intervalo de tiempo requerido para el incremento geométrico de la población, en minutos.

n - Número de períodos para incremento geométrico, sin unidad.

Sabemos que la población inicial de bacterias es 256 y que 3 horas son 6 veces 30 minutos. Entonces, tenemos la siguiente razón:

\frac{p(6\cdot \Delta t)}{p(0)} = 2^{6} (2)

Si sabemos que p(0) = 256, entonces p(6\cdot \Delta t) es:

p(6\cdot \Delta t) = 2^{6}\cdot p(0)

p(6\cdot \Delta t) = 2^{6}\cdot (256)

p(6\cdot \Delta t) = 2^{6}\cdot 2^{8}

p(6\cdot \Delta t) = 2^{14}

La población de bacterias después de tres horas es de 2^{14} bacterias.
