C Correct answer
Explanation

The pattern is: 14 * 2 = 28; 28 * 4 = 112; 112 * 6 = 672; 672 * 8 = 5376. The term 5374 is wrong; it should be 5376.

AI explanation

The logic of the series is to multiply each term by an increasing integer starting from 2. The first term, 14, is multiplied by 2 to get 28; 28 is multiplied by 4 to get 112; and 112 is multiplied by 6 to get 672. Following this pattern, 672 must be multiplied by 8, which gives 5376, but the series incorrectly lists 5374. The next multiplication of 5376 by 10 correctly produces 53760. The wrong number in the series is 5374.
