P. 12
Jawab :
a. 4, 6, 8, 10, ….
= 4 = 2 + 2 = (2 × 1) + 2
1
= 6 = 4 + 2 = (2 × 2) + 2
2
= 8 = 6 + 2 = (2 × 3) + 2
3
= 10 = 8 + 2 = (2 × 4) + 2
4
… .
= (2 × ) + 2 = 2 + 2 → = 2 + 2
b. 1, 9, 25, 49, … .
= 1 = 12 = ((2 × 1) – 1)2
1
= 9 = 32 = ((2 × 2) – 1)2
2
= 25 = 52 = ((2 × 3) – 1)2
3
= 16 = 72 = ((2 × 4) – 1)2
4
… .
2
= (2 − 1)2 → = (2 − 1)
