Question

Incira 4 meios aretimaticos entre 8 e 48

Answer 1

P.A(8,a 2 , a 3 ,a 3 ,a 4 ,a 5 ,48)
a 1 = 8 
a 6 = 48
r = ?
a 6 = a 1 + (n - 1 ).r
a 6 = 8 + (6 - 1 ).r
48 = 8 + 5.r
48 - 8 = 5 r
40 = 5 r
40/5 = r
r = 8
a 1 = 8
a 2 = a 1 + r = 8 + 8 = 16
a 3 = a 2 + r = 16 + 8 = 24
a 4 = a 2 + r = 24 + 8 = 32
a 5 = a 4 + r = 32 + 8 = 40
a 6 = a 5 + r = 40 + 8 = 48

P.A.(8,16,24,32,40,48)
