Question

Interpole oito meios aritméticos entre os números -3 e 43

Answer 1

P.A.(-3,19/9,65/9,111/9,147/9,203/9,249/9,295/9,341/9,387/9(43)
a 1 = -3
a 10 = 43
a 10 = a 1  + 9 r
43 = -3 + 9 r
43 + 3 = 9 r
46 = 9 r
46/9 = r
r = 46/9
a 1 = - 3
a 2 = a 1 + r = - 3 + 46/9 = -27 /9 + 46/9 = 19/9
a 3 = a  2 + 46/9 = 19/9 + 46/9 = 65/9
a 4 = a 3 + 46/9 = 65/9 + 46/9 = 111/9
a 5 = a 4 + 46/9 = 111/9 + 46/9 = 157/9
a 6 = 157/9 + 46/9 = 203/9
a 7 = a 6 + 46/9 = 203/9 + 46/9 = 249/9
a 8 = a 7 + 46/9 = 249/9 + 46/9 = 295/9
a 9 = a 8 + 46/9 = 295/9 + 46/9 = 341/9
a 10 = a 9 + 46/9 = 341/9 + 46/9 = 387/9 ( 43)
