Is there other way to solve this question?

Then I realized that it was even easier: Notice that the second time, you are increasing them by another 7 each. In other words…

x ----> x+7 ----> x+7+7 = 3 ----> 4 ----> 5

y ----> y+7 ----> y+7+7 = 4 ----> 5 ----> 6



I hesitated to post a similar answer last night, because “showing” ratio of progression in series is not always straightforward.

This said, it was quite clear that the progression would continue. Once you had

3/4 ----> 4/5 ----> it ought to be 5/6. Fwiw, it will also continue to 6/7 etc. The pattern is is that denominator becomes the next numerator.
