Penjelasan dengan langkah-langkah:

langkah induksi

1) n = 1

2) n = k

3) n = k + 1

1 + 3 + 5 + . . . + (2n – 1 ) = n²

i) n = 1

2(1) – 1 = 1²

2 – 1 = 1

1 = 1 (benar)

ii) n = k

1 + 3 + 5 + . . . + (2k – 1) = k²

iii) 1 + 3 + 5 + . . . + (2k – 1) + {2(k +1) -1 } = (k+1)²

k² + 2k + 2 – 1 = k² + 2k + 1

k² + 2k + 1 = k² + 2k + 1
