To find the missing number in the given sequence 2-6-30-260-3130-?, we need to identify the pattern or rule that governs the sequence.
Let's analyze the given sequence:
2, 6, 30, 260, 3130, ?
Looking at the numbers, we can notice that each number in the sequence is obtained by multiplying the previous number by a specific factor and then subtracting a certain value.
The pattern can be described as follows:
To obtain the next number, multiply the previous number by 10 and subtract the square of the previous number.
Let's apply this pattern to the given sequence:
2 * 10 - 2^2 = 20 - 4 = 16
6 * 10 - 6^2 = 60 - 36 = 24
30 * 10 - 30^2 = 300 - 900 = -600
260 * 10 - 260^2 = 2600 - 67600 = -65000
3130 * 10 - 3130^2 = 31300 - 980900 = -949600
Therefore, the missing number in the sequence is -949600.
Now, let's check the given options:
A. 24168
B. 7856
C. 46662
D. 9258
None of the options match the calculated missing number of -949600.
Hence, none of the given options are correct.
It is possible that there is an error in the question or the correct answer is not among the given options.
