Question : 1 of 40

Marks: +1, -0

9, 18, 48, 126, 369

Solution:

Concept:

In a number series, the odd term is the one that breaks the common mathematical pattern.

Explanation:

The consistent pattern is: multiply by

3

and subtract

9

9 \times 3 - 9 = 18

18 \times 3 - 9 = 45

, but the series has

48

45 \times 3 - 9 = 126

126 \times 3 - 9 = 369

48

does not fit the pattern and should be

45

Answer:

48
