Find the next term of the series.
4, 8, 28, 80, 244, ?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 728
Each term is a little more or a little less than three times the term before it, so compare every term with three times the previous one. The difference is 4 taken away and 4 added in turn:
\(4\times3-4=8\)
\(8\times3+4=28\)
\(28\times3-4=80\)
\(80\times3+4=244\)
Next: \(244\times3-4=728\)
