Question

Look at the relationship between a and b.

a 8 10 12 14
b 43 41 39 37

Which equation below describes the relationship between a and b?
A.b = 344 ÷ a
B.b = 5 × a
C.b = 51 - a

Answer 1

old question, but in case anyone stumbles upon this question in the future:

simply test each answer choice to see whether it works for all a and b values in the table

for example, a is *not* the answer because when a = 10 and b = 41, b is *not* equal to 344/a

repeat this logic with the other choices to see which one works
