Incorrect Number in the Series
The given series is: 4, 8, 28, 80, 244
We need to find out the incorrect number in the series.
Explanation
To find out the incorrect number in the series, we need to identify the pattern followed by the series. On observing the given series, we can see that:
- The first number is 4.
- The second number is obtained by multiplying the first number by 2 and adding 0. Hence, the second number is (4 x 2) + 0 = 8.
- The third number is obtained by multiplying the second number by 3 and adding 4. Hence, the third number is (8 x 3) + 4 = 28.
- The fourth number is obtained by multiplying the third number by 4 and subtracting 8. Hence, the fourth number is (28 x 4) - 8 = 80.
- The fifth number is obtained by multiplying the fourth number by 5 and adding 12. Hence, the fifth number is (80 x 5) + 12 = 412.
We can see that the fifth number obtained using the given pattern is 412, which is not equal to the given fifth number in the series, i.e., 244.
Hence, the incorrect number in the series is 244.
Therefore, the correct answer is option D (728).
