Question

Find the wrong term of the series :

$320,254,200,155,122,100,89$

• A. $155$
• B. $320$
• C. $254$
• D. $200$

Answer 1

The correct option is D $200$

Here, the difference between the two numbers is as 66, 55, 44, 33, 22 and 11.
Clearly, 254 - 55 = 199.
So, 200 is the wrong term.
Hence, option (D) is the correct answer.
