Question

Interpole onze meios aritmeticos entre 15 e 51

Answer 1

an = a1 + ( n -1) . r an

a1 = 15 + ( 1 -1) .3 = 15
a2 = 15 + ( 2 -1) .3 = 18
a3 = 15 + ( 3 -1) .3 = 21
a4 = 15 + ( 4 -1) .3  = 24
a5 = 15 + ( 5 -1) .3 = 27
a6 = 15 + ( 6 -1) .3 = 30
a7 = 15 + ( 7 -1) .3 = 33
a8 = 15 + ( 8 -1) .3 = 36
a9 = 15 + ( 9 -1) .3 = 39
a10 = 15 + ( 10 -1) .3 = 42
a11 = 15 + ( 11 -1) .3  = 45
a12 = 15 + ( 12 -1) .3 = 48
a13 = 15 + ( 13 -1) .3 = 51


PA =  (15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51)
