For this case we have to:
x: Be the variable that represents the number of adult rounds
y: Be the variable that represents the number of rounds of children
We want to know for what amount of rounds bingo costs are the same for adults and children.
Adult costs = 2x + 13
Child costs = 3y + 10
Matching:

We want the same number of rounds, x = y:

Thus, for 3 rounds the costs are the same.
Answer:
3
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
