Answer 1

The Correct Option is C

The sequence starts as follows: 138, 142, 146, 150 From 138 to 142, the difference is +4. From 142 to 146, the difference is +4. From 146 to 150, the difference is +4. Continuing the pattern, the next number should be 150 -4 = 146. . So, the correct number is 146.
