1. a
680 - 5^2 = 655
655 + 7^2 = 704
704 - 9^2 = 623
623 + 11^2 = 744
744 - 13^2 = 575

2. 10 10 20 ? 110 300 930
a) 40
b) 35
c) 45
d) 50
e) 60

2. c
10 × 0.5 + 5 = 10
10 × 1 + 10 = 20
20 × 1.5 + 15 = 45
45 × 2 + 20 = 110
110 × 2.5 + 25 = 300
300 × 3 + 30 = 930

3. 1 ? 22 188 2052 28748
a) 2
b) 3
c) 6
d) 16
e) 10

3. c
1 × 2 + 4 = 6
6 × 5 - 8 = 22
22 × 8 + 12 = 188
188 × 11 - 16 = 2052
2052 × 14 + 20 = 28748

4. 50327 7169 1215 223 76 ?
a) 1
b) 2
c) 3
d) 4
e) 8

4. d
(50327 – 144) ÷ 7 = 7169
(7169 + 121) ÷ 6 = 1215
(1215 – 100) ÷ 5 = 223
(223 + 81) ÷ 4 = 76
(76 – 64) ÷ 3 = 4
