Question

Interpolar 8 meios aritmético entre 1 e 31

Answer 1

P.A.(1;13/3;23/3;33/3;43/3;53/3;63/3;73/3;83/3;93/3) SIMPLIFICANDO
P.A(1,13/3,23/3,11,43/3,53/3,21,73/3,83/3,31)
A 1 = 1
A 10 = 31
A 10 = A 1 + (N - 1 ).R
31 = 1 + (10 - 1 ).R
31 - 1 = 9 R
30 = 9 R
9 R = 30
R = 30/9
R = 10/3
A 2 = A1 + 10/3 = 1 + 10/3 = 13/3
A 3 = 13/3 + 10/3 = 23/3
A 4 = 23/3 + 10/3 = 33/3 = 11
A 5 = 33/3 + 10/3 = 43/3
A 6 = 43/3 + 10/3 = 53/3
A 7 = 53/3 + 10/3 = 63/3  = 21
A 8 = 63/3+ 10/3 = 73/3
A 9 = 73/3 + 10/3 = 83/3
A 10 = 83/3 + 10/3 = 93/3 = 31
