The sum of three consecutive whole numbers is 111. What is the product of the smallest and the largest?
Answer and explanation
Correct answer: D. 1,368
- Step 1: The middle number is 111 ÷ 3 = 37, so the numbers are 36, 37 and 38. Step 2. 36 × 38 = 1,368. Answer: 1,368. Why not the others: 1,332: This is 36 × 37, the product of the two smallest numbers. 1,369: This is 37², the square of the middle number. 1,406: This is 37 × 38, the product of the two largest numbers.
