zad 152
N = 3n + 2
a) n = 5
N = 3 * 5 + 2 = 15 + 2 = 17
b) n = 28
N = 3 * 28 + 2 = 84 + 2 = 86
c) n = 92
N = 3 * 92 + 2 = 276 + 2 = 278
d) n = 101
N = 3 * 101 + 2 = 303 + 2 = 305
e) n = 2045
N = 3 * 2045 + 2 = 6135 + 2 = 6137
zad 153
a = 20 , b = - 16
M = (a + b)/2 = (20 -16)/2 = 4/2 = 2
a = - 120 , b = 48
M = (a + b)/2 = (- 120 + 48)/2 = - 72/2 = - 36
a = - 4/8 , b = - 3,2)
M = (a + b)/2 = (- 4,8 - 3,2)/2 = - 8/2 = - 4
