39 diletakan di tengah bilangan.
37, 39, 41
bilangan terbesar 41, bilangan terkecil 37, jdi jumlahnya 41 + 37 = 78
maaf kalau salah
Bilangan 1 = x
Bilangan 2 = x +2
Bilangan 3 = x +4
Maka,
x +x +2 +x +4 = 117
x +x +x +2 +4 = 117
3x +6 = 117
3x = 117 -6
3x = 111
x = 111/3
x = 37
Bil. 1 = 37
Bil. 2 = x +2
= 37 +2
= 39
Bil. 3 = x +4
= 37 +4
= 41
Maka, bilangan terbesar dan terkecil secara berurutan adalah 41 dan 37.
Itu jawabannya.
