Select the option that completes the series correctly. 12, 26, 54, 110, 222, ______
446
446 is correct.
When each term is roughly double the one before it, check whether a fixed number is added or subtracted after doubling.
Each term is twice the previous term plus 2: \(12 \times 2 + 2 = 26\), \(26 \times 2 + 2 = 54\), \(54 \times 2 + 2 = 110\).
Continuing, \(110 \times 2 + 2 = 222\).
So the next term is \(222 \times 2 + 2 = 446\).
