Please kaka format the question properly. It is really easy to do

Thank you so much

Are you sure the terms in the question are correct ? I did find an equal question but different values.

Let me know

A. The quantity in Column A is greater
B. The quantity in Column B is greater
C. The two quantities are equal
D. The relationship cannot be determined from the information given


The first 13 terms of SEQUENCE S: 2, 3.5, 5, 6.5, 8, 9.5, 11, 12.5, 14, 15.5, 17, 18.5, 20
The first 13 terms of SEQUENCE A: 18.5, 17, 15.5, 14, 12.5, 11, 9.5, 8, 6.5, 5, 3.5, 2, 0.5

We can see that the two sequence share 12 terms
If we subtract those 12 shared terms from each sequence, we get:
The first 13 terms of SEQUENCE S: 2, 3.5, 5, 6.5, 8, 9.5, 11, 12.5, 14, 15.5, 17, 18.5, 20
The first 13 terms of SEQUENCE A: 18.5, 17, 15.5, 14, 12.5, 11, 9.5, 8, 6.5, 5, 3.5, 2, 0.5

We can see that Quantity A is greater.

Answer: A
