Question Numbers: 133-135

Below given are series I such that logic followed in series ll is same as the logic followed in series I.

Series I: 60, 120, 24, 48, 9.6, 19.2

Series II: 100, W, X, Y, Z, 32

Question : 134 of 155

Marks: +1, -0

Solution:

Concept:

The series follows an alternating pattern: multiply by

2

, then divide by

5

, repeated throughout.

Explanation:

Series I is

60, 120, 24, 48, 9.6, 19.2

60 \times 2 = 120

120 \div 5 = 24

24 \times 2 = 48

48 \div 5 = 9.6

9.6 \times 2 = 19.2

So the same logic applies to Series II:

100, W, X, Y, Z, 32

100 \times 2 = 200 = W

200 \div 5 = 40 = X

Thus, the first term of Series III is

W - X = 200 - 40 = 160

Now apply the same pattern to Series III:

160 \times 2 = 320

320 \div 5 = 64

(third term)

So Series III starts as

160, 320, 64, \dots

Therefore, the third term of Series III is

64

Answer:

64
