bilangan kelipayan 4 antara 100dan 300 adalah yg simpel aja

104,108,112, 116, 120, 124, 128, 132, 136, 140, 144, 148, 152, 156, 160, 164, 168, 172, 176,180, 184, 188, 192, 196, 200,204, 208, 212, 216, 220,224, 228, 232, 236, 240, 244, 248, 252, 256, 260, 264, 268, 272, 276,280, 284, 288, 292, 296, 300

kelipatan 4 antara 100 dan 300
104, 108, 112 . . .. . 296
U1= 104
b= 4
Un= 296
Un = a + (n-1)b
296 = 104 + (n - 1) 4 (di bagi 4)
74 = 26 + (n - 1)
74 - 26 = n - 1
48 = n - 1
n = 48 + 1 = 49
S49 = 24,5 (104 + 296) /2
S49 = 26,5 ( 200)
S49 = 10600
