Q2. What should come next? 150, 130, 112, 96, 82, ?
Answer: 70
The differences are 20, 18, 16, 14. Following the pattern, the next difference should be 12, so 82 - 12 = 70.
Answer: 2 # 3 = 16
For 4 # 5 = 81, 81 = 9^2; for 6 # 7 = 169, 169 = 13^2; for 3 # 4 = 49, 49 = 7^2. These fit the pattern of (a+b)^2. But 2 # 3 = 16 = 4^2 does not match the same relation, so it is the odd one out.
