Answer :
Final answer:
The sequence alternates between segments of decreasing by 1 three times and then halving. By following this pattern, the next number in the sequence is C.20.
Explanation:
This sequence has alternating segments where the number decreases by 1 three times and then gets halved. For the first segment, we start with 350, decrease by one, three times to get 347 and then it was halved to get 174. This process repeats until we reach 40. To find the next number, we should halve 40, which gives 20. So the correct answer is C. 20.
