Series and Odd Man out Practice Test 8

Question : 7 of 16

Marks: +1, -0

34, 11, 3.3, 0.77, -0.07

Solution:

Concept:

A wrong-number series follows a fixed rule; one term breaks the pattern.

Explanation:

The rule is: subtract

1

from the previous term and divide the result by

3

Check:

(34 - 1) \div 3 = 11

Next term should be

(11 - 1) \div 3 = 10/3 = 3.33

But the series has

33

, which does not match.

The later terms follow the rule:

(3.33 - 1) \div 3 \approx 0.77

and

(0.77 - 1) \div 3 \approx -0.07

33

is the wrong number.

Answer:

33

(Option C).
