Answers and explanations
- 48. Every term is twice the previous one.
- $10. Each apple costs $2, so five cost $10.
- 14. Multiply first: 4 × 3 = 12. Then 8 + 12 − 6 = 14.
- 63. The ones digit is 3, and the tens digit is 6; together they add to 9.
- $66. The discount reduces $80 to $60. Ten percent tax on $60 is $6, making $66.
Why short puzzles are useful
Sequences train pattern recognition. Word problems make you translate language into numbers. Arithmetic challenges reward remembering the order of operations, while discounts show why percentages must be applied to the correct amount. How many did you solve on your first attempt?
