3, 9, 27, 81, … What is the next number in the sequence?

Is it

a) 108

b) 130

c) 162

d) 243


If you picked d), you would be correct.

If you picked a) or b) or c), you would still be correct.

Have a look at this fairly short article (5 pages) by Donald White of KSU titled “When Every Answer is Correct: Why Sequences and Number Patterns Fail the Test”
