jumlah bilangan antara 200 Dan 500 yg habis dibagi 6 adalah

U1 = a = 204
U50. = 498
U50= 50/2 X (204 + 498)
= 25 X 702
= 17.550
maaf klo salh

204, 210, 216, ....... 498

498 : 6 = 83
204 : 6 = 34

83 - 34 = 49

Jumlah Suku ada 49

U1 atau a = 204

Beda = U2 - U1 = 210 - 204 = 6

Sn = n/2 [2.a + (n-1).b]
S49 = 49/2 [2.204 + (49-1).6
S49 = 49/2 [408 + 48.6]
S49 = 49/2 [408 + 288]
S49 = 49/2 [696]
S49 = 49/2 × 696
S49 = 17.052

Semoga membantu :)
