How can it not be B i.e 5.2? It will make a = 4.45 which is possible right?

Keep in mind that a has to be greater than 4.6. If a is 4.45, then 2a is 8.9. Notice that 2a is listed after 9.2, which means that 2a is greater than 9.2. If a = 4.45, then 2a will not be greater than 9.2, so a cannot be 4.45

a could be 4.1 as well, right?

Hi there :)

Good question! It turns out that a cannot equal 4.1. If that were the case, then 2a = 8.2 and the values would not be listed in increasing order.

Hope that helps :)
