1. Jawaban ShanedizzySukardi
Materi: Barisan dan Deret
Dikelompokkan sbb
(1 + 100) + (2 + 99) + (3 + 98) + (4 + 97) + ..... + (50 + 51)
= 101 + 101 + 101 + 101 + ... + 101 (sebanyak 50)
= 101 × 50
= 5050 -
2. Jawaban ErikCatosLawijaya
Mapel : Matematika
Kelas : IX SMP
Bab : Barisan dan deret
Pembahasan :
1 + 2 + ... + 100 = S100
1 + 2 + ... + 100 = 100/2(1 + 100)
1 + 2 + ... + 100 = 50(101)
1 + 2 + ... + 100 = 5050
