Question

interpode 6 meios aritmeticos entre 62 e 97

Answer 1

P.A.(62,a 2 a3 a 4 a 5 a 6 a 7  97)
a 1 = 62
a 8 = 97
a 8 = a 1 + (n - 1 ).r
a 8 = 62 + (8 - 1 ) . r
a 8 = 62 + 7 r
62 + 7 r = a 8
62 + 7 r = 97
7 r = 97 - 62
7 r = 35
r = 35/7
r = 5

a 1 = 62
a 2 = 62 + 5 = 67
a 3 = 67 + 5 = 72
a 4 = 72 + 5 = 77
a 5 = 77 + 5 = 82
a 6 = 82 + 5 = 87
a 7 = 87 + 5  = 92
a 8 = 92 + 5 = 97

P.A.(62,67,72,77,82,87,92,97)
