Answer :
Final answer:
In this numerical series, each subsequent number appears to be the result of adding an amount that is double the previous amount added. However, using this pattern to predict the next number in the series results in a value, 167, that is not among the given options.
Explanation:
It appears that the given sequence is increasing by a pattern. The first raise is from 12 to 17 (which is equivalent to addition of 5), the next is from 17 to 27 (addition of 10), then from 27 to 47 (addition of 20), and 47 to 87 (addition of 40). The pattern progresses in such a way that each subsequent number in the sequence is the result of adding an amount that is double the previous amount added.
Trying to foresee the next number in the sequence, and utilising the double-addition pattern, we would need to double the recent addition number, which is 40. As a result, 80 will be added to 87 giving us 167.
Unfortunately, 167 is not among the options given in your question for the next sequence number. So there might be an error or misunderstanding in either the sequence or the options provided.
