The correct option is B A200
The given sequence is A125, A150, A175.
Each term contains A as the first letter.
Hence, the last term should also contain A as the first letter.
The numbers in the sequence are 125, 150, 175.
Let us find the difference between the terms.
Difference between the 1st and the 2nd terms = 150 - 125 = 25
Difference between the 2nd and the 3rd terms = 175 - 150 = 25
Therefore, to find the next term, we have to add 25 to the numeric part of the term.
Hence, the next numeric part in the last term is 175 + 25 = 200, and the term is A200.
Hence, the next term in the pattern is A200.
