Explanation
To find the missing number in the series 4, 28, ?, 1372, we need to identify the pattern or rule governing the sequence.
Looking at the given numbers, we can observe that each subsequent number is obtained by multiplying the previous number by 7:
4 * 7 = 28
28 * 7 = 196
196 * 7 = 1372
Therefore, the missing number in the series is 196.
The correct answer is B) 196.
