The first term in a series of numbers is 50. Each subsequent term is 1/2 the term before it if it was even. or 1/2 rounded up to the next whole number if it is odd. What is the 3rd number in this sequence?

a)13

b)24

c)30

d)40

i dont get this. so, the second number is 45, and the third is 1/2 x 45= 22.5, which would be close to b) 24?

the answer is A.
