Answer:
3
Step-by-step explanation:
write them out least to greatest- 1 2 3 4 5
then mark out one at a time from front and back- 1 2 3 4 5
then you get one number and that number is 3
32/a = a/2
a^2 = 64
a = 8
b^2 = 8^2 + 2^2
b^2 = 64 + 4
b^2 = 68
b = 2√17
answer is the first option
a = 8, b = 2√17
