Diketahui P(n) : 0+2+4+⋯+2(n−1)≤2n(n−1)P\left(n\right)\ :\ 0+2+4+\dots+2(n-1)\leq2n(n-1). Jika P(n)P\left(n\right) benar untuk n=kn=k, artinya ....

A

P(k):0+2+4+⋯+2(k−1)≤2k(k−1)P(k):0+2+4+\dots+2\left(k-1\right)\le2k\left(k-1\right)

B

P(k):0+2+4+⋯+2(k−1)≤2k(k+1)P(k):0+2+4+\dots+2\left(k-1\right)\le2k\left(k+1\right)

C

P(k):0+2+4+⋯+2k≤2k(k−1)P(k):0+2+4+\dots+2k\le2k\left(k-1\right)

D

P(k):0+2+4+⋯+2k≤2k(k+1)P(k):0+2+4+\dots+2k\le2k\left(k+1\right)

E

P(k):0+2+4+⋯+2(k+1)≤2k(k−1)P(k):0+2+4+\dots+2\left(k+1\right)\le2k\left(k-1\right)
