Se forman varios triángulos con fósforo uno después de otro escribe una expresión numérica que representa el número de fósforo según el número de triángulos
Answers
La expresión numérica que representa el número de fósforos según el número de triángulos es: x=2n+1
Vamos a suponer que los triángulos se disponen de la manera mostrada en el diagrama (ver diagrama adjunto)
Cuando se construye el primer triángulo vamos a necesitar de 3 fósforos.Cuando se construye el segundo triángulo vamos a necesitar de 2 fósforos adicionales por lo que obtenemos 3+2=5 fósforos.Cuando se construye el tercer triángulo, se necesitan 2 fósforos adicionales, por lo que obtenemos 3+2+2=7Cuando se construye el cuarto triángulo se necesitan 2 fósforos adicionales y tenemos 3+2+2+2=9En este caso vamos viendo un patrón, por cada nuevo triángulo vamos necesitando dos fósforos adicionales.
Cuando tenemos varios números que presentan un patrón y el patrón es que la distancia entre dos números consecutivos es la misma, entonces estamos hablando de una secuencia aritmética. Las secuencias aritméticas tienen la forma general:[tex]x_{n}=a+d(n-1)[/tex]
En este caso vamos a definir dos variables:
x = número de fósforos
n = número de triángulos
El patrón que vimos arriba se puede escribir de la siguiente manera:
x=3+2n
pero mucho ojo, esta fórmula es válida únicamente si empezamos a contar de n=1 triángulo adicional (osea cuando tenemos 2 triángulos). Si usamos n=1 obtenemos:
x=3+2(1)=5 (el cual es el resultado para 2 triángulos, no 1)
Esto se puede arreglar restándole un 1 a la x para que de esa forma, la fórmula sea válida cuando usamos x=1 triángulo, así que obtenemos:
x=3+2(n-1)
(Esta es la forma general de una secuencia aritmética.)
Ahora bien, esta fórmula puede ser simplificada usando álgebra, así que obtenemos:
n=3+2x-2
lo cual nos da:
n=2x+1
por lo que la expresión numérica que representa el número de fósforos según el número de triángulos es: n=2x+1

I met this hella weird cryptic dude who interviewed me and gave me this puzzle. Solve it within 12 hours and ill let you know what he says. Row zero (0) must be solved.
Your final code should contain nine (9) letters, and one (1) number. The number two (2) has been given to you as the first character in your final code.
Disclaimer: This code is foreign, meaning it is not a word or sentence from any language. It is a string of specific characters. You will be given a second, simpler cipher to decrypt that reads "graph." It has already been solved for you. Understanding how this smaller chart produces "graph" will grant you the deciphering method used for the large cipher.
This cipher must be completed at maximum twenty-four (24) hours from reception. Failure to complete in this time will result in re-calibration via interviewing, not disqualification, should you (as a participant) wish to continue.
To validate this code, or request further clarification, refer to this account.
Speaking to any personnel regarding the cipher without supervision is strictly prohibited, and will result in disqualification.
HINTS:
"^," or Carrots, signify a capitalized letter in the string. Capitalization matters.
Everything you need to complete this cipher is given here.
Only very basic math was used to encrypt this key (Multiplication and Division).
You are not allowed to ask others for help without the supervision of the employment center. We will know if you've leaked, or gave any information out regarding this Cipher. We are entrusting you with it.

6558/6
1093 tickets
Answer:
The band have to sell 1093 Ticket to meet its goal
Step-by-step explanation:
Total cost = $6,558
Per Ticket cost =$6
formula:
No of Tickets = Total cost of Ticket ÷ Per Ticket Cost
= 6558 ÷ 6
No of Tickets = 1093
Check:
Total Cost = No of Ticket × Per ticket cost
= 1093 × 6
Total Cost =$6558
