• B. 149
• C. 151
• D. 160

Answer 1

The Correct Option is A

First number divisible by 3 that is greater than or equal to 50 is 51.
Last number divisible by 3 that is less than or equal to 500 is 498.

Number of terms in the sequence is calculated as:
(498 - 51) / 3 + 1 = 447 / 3 + 1 = 149 + 1 = 150

Thus, the correct answer is:

Answer: 150
