Question

interpolar 6 meias aritmeticas entre 8 e -21 nesse ordem​

Answer 1

Resposta:

Explicação passo a passo:

8,_,_,_,_,_,_,-21

a1=8

a8=-21

an=a1+(n+1)r

-21=8+(8-1).r

-21=8+7r

-21-8=7r

7r=-29

r=-29/7

a1=8

a2=8-29/7=56/7-29/7=27/7

a3=27/7-29/7=-2/7

a4=-2/7-29/7=-31/7

a5=-31/7-29/7=-60/7

a6=-60/7-29/7=-89/7

a7=-89/7-29/7=-118/7

a8=-118/7-29/7=-147/7=-21
