In the following question, a number series is given, after the number series, a number and then A, B, C, D and E are given. Complete the number series starting from the given number based on the pattern of the original number series and choose correct option. 27 35 59 107 187 307 18 A B C D E What will come in place of ‘E’? Correct Answer 298

Solution:

The pattern of the original number series is

⇒ 27 + (32 – 1) = 35

⇒ 35 + (52 – 1) = 59

⇒ 59 + (72 – 1) = 107

⇒ 107 + (92 – 1) = 187

⇒ 187 + (112 – 1) = 307

According the pattern of the above series the number series starting from the given number

would be as:

⇒ A = 18 + (32 – 1) = 26

⇒ B = 26 + (52 – 1) = 50

⇒ C = 50 + (72 – 1) = 98

⇒ D = 98 + (92 – 1) = 178

⇒ E = 178 + (112 – 1) = 298

∴ The required number in place of E would be 298
