Correct Answer: 69
Solution :
Given:
9, 13, 21, 33, 49, x
Add the consecutive multiples of 4 to each term to obtain the next term –
9 + (4 × 1) = 9 + 4 = 13;
13 + (4 × 2) = 13 + 8 = 21;
21 + (4 × 3) = 21 + 12 = 33;
33 + (4 × 4) = 33 + 16 = 49;
49 + (4 × 5) = 49 + 20 = 69
So, 69 is the missing number in the series. Hence, the fourth option is correct.
