Direction: Find out the missing number in the series.
3, 9, 27, 81, __________
- 324
- 243
- 210
- 162
Answer and explanation
Correct answer: B - 243
Each term is 3 times the one before (the powers of 3): 3, 9, 27, 81. The next term is 81 x 3 = 243. 162 doubles 81 instead of tripling it, and 324 multiplies it by 4.
