En nuestro colegio, después de cada recreo cada grupo de alumnos limpia una zona del mismo. Tenemos un patio cuadrado y el feje de estudios propuso que cada curso limpiara la zona que puedes ver a continuación. Esta era la idea inicial pero pronto llegaron los problemas. ¿Sabrías decir quiénes fueron los primeros en quejarse? ¿Por qué?

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
