### Question 1

Examine this series: 5, 12, 60, 340. If another series is written with the same rule, what number would come in the place E: 7, A, B, C, D, E ?

**A**

172

**B**

3224

**C**

1012

**D**

20164

**Soln.**

**Ans: d**

Number 20164 will come in place of (D). Rule is: 5 X 8 - 28 = 12, then 12 X 7 - 24 = 60, then 60 X 6 - 20 = 340, and so on. On this pattern, A = 7 X 8 - 28 = 28, B = 28 X 7 - 24 = 172, C = 172 X 6 - 20 = 1012, D = 1012 X 5 - 16 = 5044, E = 5044 X 4 - 12 = 20164.

### Question 2

In the following number series, one of the numbers does not fit into the series. Find the wrong number.

35, 118, 280, 600, 1238, 2504, 5036

**A**

118

**B**

280

**C**

600

**D**

1238

**Soln.**

**Ans: d**

Number 1238 is wrong and should be replaced by 1236. The differences in successive numbers are 83, 162, 320, 636, 1268, 2532. The differences in these are 79, 79 X 2 = 158, 158 X 2 = 316, 316 X 2 = 632, 632 X 2 = 1264, you can see how complicated is this series yourself!
