Responder:
4n-1
Explicación paso a paso:
Dada la secuencia
3, 7, 11, 15, 19, 23 ..
El enésimo término si la secuencia se expresa como;
Tn = una + (n-1) d
a es el primer término = 3
n es el número de términos
d es la diferencia común = 7-3 = 11-7
d = 4
Sustituir
Tn = 3+ (n-1) (4)
Tn = 3 + 4n-4
Tn = 4n-1
Por lo tanto, el enésimo término de la secuencia es 4n-1

Answer:
Step-by-step explanation:
First convert the transmit power into μW, considering 1 W = 1000000 μW:
- 0.35 W = 0.35*1000000 μW = 350000 μW
Find how many factors of 10 the power dropped:
Find the distance:
I think 100% profit means she got the gloves for free so all her revenue was profit. That can't be right. Let's assume 'profit on the cost' means a 100% markup, meaning she sold the gloves for £8.
That means she sold the skirt for £40.
She made 20% profit on the total cost t so
1.2 t = 48
t = 48/1.2 = 40
Since she spent £4 on the gloves that means she spent £36 on the skirt she sold for £40.
So she made £4 on a cost of £36 for a percentage of 1/9=.11111...
Answer: 11.1%
