If Q is an odd number and

Sam Kinsman

Hi Sonika,

Yes, we can find the answer by plugging in numbers. However, we would need to work with each answer choice, to see which one works.

For example, if Q=3, we would have three integers: 119, 120, 121. The largest integer would be 121.

We would then plug Q=3 into each answer choice, to see which answer choice gives us a result of 121. A does that, so A must be correct.

Hi Hichem :)

While it seems like Mike says 20 instead of 120 at about 0:30 in the explanation, he is referring to the median of 120 at that point. Since 120 is the median of a set with an odd number of values, we know that 120 will be the middle number when we write the values in ascending order. For that reason, if there are n numbers above 120, there must also be n numbers below 120.

I hope this helps :)

Hi Deethu. Yes, changing 120 to a different integer doesn't change how the problem works. But 120 shouldn't be difficult to work with either, since we are simply counting consecutive integers after it. 119, 120, 121, for example, are just as easy to work with.
