Complete the series:
52, 58, 60, 66, 70, ?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 76
The differences between the terms follow two rules taken in turn: every other step adds 6, and the steps in between add 2, then 4.
\(52+6=58\)
\(58+2=60\)
\(60+6=66\)
\(66+4=70\)
The next step is again a “\(+6\)” step: \(70+6=76\)
