Which number continues the sequence? 3, 46, 7, 41, 11, 36, ...
Answer and explanation
Correct answer: C. 15
- Step 1: Two patterns alternate: +4 in the odd places and -5 in the even places. Step 2. The next number belongs to the first pattern: 11 + 4 = 15. Answer: 15. Why not the others: 31: the second pattern was continued instead of the first. 19: the step was added twice. 11: the step was subtracted.
