Q:

Find the odd one out of the floowing number series?

270, 261, 279, 252, 289, 243

A) 270 B) 279
C) 289 D) 243
 
Answer & Explanation Answer: C) 289

Explanation:

Here the given number series is 270, 261, 279, 252, 289, 243

270 - 9 = 261

261 + 18 = 279

279 - 27 = 252

252 + 36 = 288 (not equals to 289)

288 - 45 = 243

 

Hence, the odd number in the given number series is 289.
