Answer:
1. 486, 1458
2. 1, ⅕
3. -1, ⅙
4. 1/243, 1/729
5. 1, ⅙
6. 486, -1458
7. 8/125, 8/625
8. ¼, 1/16
9. -1/64, -1/256
10. 4, 4√2
Step-by-step explanation:
1. r = a2/a1
r = 18 ÷ 6
r = 3
2. r = a2/a1
r = 125/625
r = 1/5
3. r = a2/a1
r = 216/-1296
r = -1/6
4. r = a2/a1
r = ⅑/⅓
r = ⅑ × 3
r = 3/9
r = ⅓
5. r = a2/a1
r = 216/1296
r = 1/6
6. r = a2/a1
r = -18/-6
7. r = a2/a1
r = 8/40
8. r = a2/a1
r = 16/64
r = 1/4
9. r = a2/a1
r = -1/-4
10. r = a2/a1
r = (√2)/1
r = √2
