What is the next term in the decreasing sequence: 128, 64, 32, 16, 8, ___?
Answer and explanation
Correct answer: C. 4
- Step 1: Each term is halved: 128/2 = 64, 64/2 = 32, 32/2 = 16, 16/2 = 8. Step 2. 8/2 = 4. Answer: 4, dividing the preceding term by 2. Why not the others: 2 skips a step; 6 subtracts 2.
