bilnabila20
A) n² (n+1)² Jika n = 1 1² (1+1)² = 1. 2² = 4 Jika n = 2 2² (2+1)² = 4.3² =4.9=36 Jika n = 3 3² (3+1)² = 9.4² = 9.16=144 Jika n = 4 4² (4+1)² = 16.5² =16.25=400 Jika n = 5 5² (5+1)² = 25.6²=25.36=900
Jika n = 1
1² (1+1)² = 1. 2² = 4
Jika n = 2
2² (2+1)² = 4.3² =4.9=36
Jika n = 3
3² (3+1)² = 9.4² = 9.16=144
Jika n = 4
4² (4+1)² = 16.5² =16.25=400
Jika n = 5
5² (5+1)² = 25.6²=25.36=900
