Identify the missing item in the series: 2, 6, 12, 20, ? , 42?
Explanation
The given series is:
2, 6, 12, 20, ?, 42
Let's identify the pattern:
2 + 4 = 6
6 + 6 = 12
12 + 8 = 20
20 + 10 = 30
30 + 12 = 42
The pattern involves adding consecutive even numbers: +4, +6, +8, +10, +12.
The missing item is 30.
