Question

ubique 4 medios aritmeticos entre -5 y +5​

Answer 1

Respuesta:

formula

an = a1 + (n-1) r

an = ultimo termino    an = 5

a1 = 1er termino          a1 = -5

n = 4+2 = 6   n= numero de treninos

r= razon = ?

(an -a1) / (n-1) = r

(5 -(-5))/(6 -1) = r

(5+5)/5 = r

10/5 = r

2 = r

1er termino = -5

2do termino = -5 +2 = -3

3er termino = -3+2 = -1

4to termino = -1+2 = 1

5to termino = 1+2 = 3

6to termino = 3+2 = 5

queda  -5. -3. -1. 1. 3. 5
