The sum of three consecutive whole numbers is 78. What is the largest of the three?
Answer and explanation
Correct answer: D. 27
- Step 1: Let the numbers be n - 1, n, n + 1. Their sum is 3n = 78, so n = 26. Step 2. The largest is n + 1 = 27. Answer: 27. Why not the others: 26 is the middle number; 28 would give a sum of 81; 25 is the smallest.
