Find the missing term: 3 : 27 :: (?) : 125
Explanation
Explanation
Notice that 27 is the cube of 3 (3×3×3 = 27). The same rule should apply to the second pair, so we need a number whose cube is 125. Since 5×5×5 = 125, the missing number is 5, option (2).
PRO TIP
Re-check your working by substituting the answer back into the original question.
