Series and Odd Man out Practice Test 1

Question : 5 of 40

Marks: +1, -0

9, 35, 210, 1470, 11760

Solution:

Concept:

In a number series, one term may break a consistent multiplication pattern.

Explanation:

Check the ratios between consecutive terms.

35 \div 9

is not a whole number, so

9

does not fit the pattern.

From

35

onward:

210 \div 35 = 6

1470 \div 210 = 7

, and

11760 \div 1470 = 8

So the intended pattern is

\times 5, \times 6, \times 7, \times 8

The first term should be

7

because

7 \times 5 = 35

Therefore,

9

is the odd term.

Answer:

The odd term is

9

(Option A).
