Odpowiedź:
a) A = { 0,2,4,6,8 }
bo 2*0 = 0 2*1 = 2 2*2 = 4 2*3 = 6 2*4 = 8
b) B = { 0, -1,-2,-3, - 4, ... }
c) C = { 1, [tex]\frac{1}{2} , \frac{1}{3} , \frac{1}{4} ,[/tex] ... }
d) D = { 3, 5, 7, ... }
bo -2*(-1) + 1 = 2 + 1 = 3
-2*(-2) + 1 = 4 + 1 = 5
-2*(-3) + 1 = 6 + 1 = 7 itd.
Szczegółowe wyjaśnienie:
" Life is not a problem to be solved but a reality to be experienced! "
