x + (x+2) + (x+4) + (x+6) = 100
4x + 12 = 100
4x = 100-12
4x = 88
x = 22
bilangan terbesar = x +6
= 22 + 6
= 28
jadi ada 4 bilangan yaitu 22, 24, 26, 28
#semoga bermanfaat
misalkan a adalah bilangan pertama = 1
Sn = 100
Sn = n/2 (2a + (n-1)b)
Sn = n/2 (2 + (n-1)2)
100= n/2 (2 + 2n - 2)
100 x 2 = n (2n)
200 = 2n²
200 : 2 = n²
100 = n²
√100 = n
n = 10
Ada 10 bilangan , maka U10 = ??
a + 9b = 1 + 9.2
= 19
Bilangan terbesar adalah 19
