Question 12

Find out the wrong number from the given series.
5,27,61,122,213,340,509

Solution

The pattern followed here is,

$$2^{3} - 3 = 5$$

$$4^{3} - 3 = 61$$

$$5^{3} - 3 = 122$$

$$6^{3} - 3 = 213$$ .......

$$3^{3} - 3= 24$$ (but 27 is given in the option)

Hence, option A is the correct answer.
