Question

Find out the wrong figure in the series: 325, 259, 202, 160, 127, 105, 94

• A. 202
• B. 94
• C. 127
• D. 259

Hint:

In series problems, identifying the pattern in the differences between consecutive terms can help spot the outlier.

Answer 1

The Correct Option is A

The series is: 325, 259, 202, 160, 127, 105, 94.
Now, let's check the difference between consecutive terms:
- 325 - 259 = 66
- 259 - 202 = 57
- 202 - 160 = 42
- 160 - 127 = 33
- 127 - 105 = 22
- 105 - 94 = 11
The differences seem to be reducing in a pattern, but the difference between 259 and 202 is 57, which doesn't fit the pattern of decreasing differences. Hence, 202 is the wrong figure in the series.

Answer 2

We are given a series: 325, 259, 202, 160, 127, 105, 94
We need to identify the wrong number in this sequence.

Step 1: Find the differences between consecutive terms
259 - 325 = -66
202 - 259 = -57
160 - 202 = -42
127 - 160 = -33
105 - 127 = -22
94 - 105 = -11

So, the differences are:
-66, -57, -42, -33, -22, -11

Now observe the pattern in differences:
From -66 to -57 → +9
From -57 to -42 → +15
From -42 to -33 → +9
From -33 to -22 → +11
From -22 to -11 → +11

This is inconsistent and does not follow a simple arithmetic or geometric pattern.

Alternative Approach: Try reconstructing a logical series
Let’s try building a new consistent series from 325 using a decreasing pattern:
325 → -66 → 259
259 → -51 → 208
208 → -42 → 166
166 → -33 → 133
133 → -22 → 111
111 → -11 → 100

This gives us: 325, 259, 208, 166, 133, 111, 100
Clearly, 202 in the original series breaks this potential pattern.

Conclusion:
The wrong number in the given series is 202.
