Question

interpole 12 meios aritmeticos entre 8 e 73 ?

Answer 1

(8, a2,a3,a4,a5,a6,a7,a8,a9,a10,a11,a12,a13,73);
a1 = 8; An = 73; n=14;
an = a1 + (n -1). r;
a14= a1 + (14-1).r;
a14 =a1 + 13r;
73= 8+13r;
73-8= 13r;
65=13r;
13r= 65;
r = 65/13;
r=5;
a2 = a1+r; a2= 8+5; a2= 13;
a3 = a2+r; a3= 13+5; a3 =18;
Resp.:

(8,13,18,23,28,33,38,43,48,53,58,63,68,73)
