Question 13

Select the set in which the numbers are related in the same way as are the numbers of the following set.
8, 9, 145

Solution

8,9,145

Multiply the first two numbers = 8*9 = 72 then double it = 72*2 = 144

Then difference of the first two numbers= 9-8 =1

Add it to the first number = 144 + 1 = 145

The same goes with, 6,7,85

6*7 = 42*2=84

7-6=1

84+1=85
