Question 5

# Select the set of numbers that is similar to the following set of numbers.(13, 40, 121)

Solution

$$\left(13,40,121\right)\longrightarrow\ 13\times\ 3+1=40,\ 40\times3+1=121.$$

Similarly, $$\left(5,16,49\right)\longrightarrow\ 5\times\ 3+1=16,\ 16\times\ 3+1=49.$$

So, A is correct choice.
