D Correct answer
Explanation

Pattern: x*4-2. 2*4-2=6, 6*4-2=22, 22*4-2=86, 86*4-2=342 (not 340). 342*4-2=1366. The wrong term is 340.

AI explanation

Each number in the sequence is multiplied by 4, and then 2 is subtracted to get the next term. Applying this to the first few terms, 2 times 4 minus 2 is 6, 6 times 4 minus 2 is 22, and 22 times 4 minus 2 is 86. Using the formula for 86, we calculate 86 times 4 minus 2 to get 342, meaning 340 is the incorrect term.
