Answer Key — OLSAT Grade 7

1. 1. B — The amount added grows by 1 each step. Adding 5 to 14 gives 19.
2. 2. B — Each step, one more shape appears each time. Continuing one more step gives B. The others: A steps backward in the series; C the right figure with the wrong fill; D the right step on the wrong shape; E repeats the last figure instead of stepping on.
3. 3. B — The relationship is "part to its whole." room → house, so string → guitar.
4. 4. B — Each number is multiplied by 2. 32 × 2 = 64.
5. 5. E — Each step, the figure alternates big and small. Continuing one more step gives E. The others: A the right figure with the wrong fill; B repeats the last figure instead of stepping on; C does not continue the series; D the right step on the wrong shape.
6. 6. B — The relationship is "part to its whole." wheel → car, so tooth → comb.
7. 7. B — Each number is multiplied by 2. 24 × 2 = 48.
8. 8. A — Each step, the fill moves one step through the cycle (light to dark, then starting over). Continuing one more step gives A. The others: B jumps two steps ahead; C steps backward in the series; D the right step on the wrong shape; E repeats the last figure instead of stepping on.
9. 9. C — The relationship is "what it grows or turns into." cub → bear, so bud → flower.
10. 10. A — Each number is multiplied by 3. 108 × 3 = 324.
11. 11. E — Each step, the fill moves one step through the cycle (light to dark, then starting over). Continuing one more step gives E. The others: A the right step on the wrong shape; B jumps two steps ahead; C repeats the last figure instead of stepping on; D steps backward in the series.
12. 12. C — The relationship is "part to its whole." string → guitar, so finger → hand.
13. 13. A — These are square numbers: 4², 5², … Next is 8² = 64.
14. 14. B — Each step, the fill moves one step through the cycle (light to dark, then starting over). Continuing one more step gives B. The others: A repeats the last figure instead of stepping on; C the right figure with the wrong fill; D jumps two steps ahead; E the right step on the wrong shape.
15. 15. A — The relationship is "what it grows or turns into." puppy → dog, so acorn → oak.
16. 16. B — Each number is multiplied by 3. 81 × 3 = 243.
17. 17. A — Each step, the fill moves one step through the cycle (light to dark, then starting over). Continuing one more step gives A. The others: B jumps two steps ahead; C the right figure with the wrong fill; D the right step on the wrong shape; E repeats the last figure instead of stepping on.
18. 18. B — The relationship is "worker to their workplace." actor → stage, so judge → court.
19. 19. B — These are square numbers: 3², 4², … Next is 7² = 49.
20. 20. A — Each step, one more shape appears each time. Continuing one more step gives A. The others: B repeats the last figure instead of stepping on; C steps backward in the series; D the right figure with the wrong fill; E the right step on the wrong shape.
