Question

interpore quatro meios aritmeticos entre -12 e 48

Answer 1

n an = a1 + ( n -1) * r        an
1 an = -12 + ( 1 -1) * 12   -12
2 an = -12 + ( 2 -1) * 12      0
3 an = -12 + ( 3 -1) * 12    12
4 an = -12 + ( 4 -1) * 12    24
5 an = -12 + ( 5 -1) * 12    36
6 an = -12 + ( 6 -1) * 12    48


PA = {-12, 0, 12, 24, 36, 48}
