Question
Select the set in which the numbers are related in the
same way as are the numbers of the following set. (4, 152, 6)Solution
The logic is: Difference of cube of first term and third term results in middle term. 4³ = 64 and 6³ = 216; 216 – 64 = 152 2³ = 8 and 6³ = 216; 216 – 8 = 208 The logic is: Difference of cube of first term and third term results in middle term. 4³ = 64 and 6³ = 216; 216– 64 = 152 2³ = 8 and 6³ = 216; 216 – 8 = 208
