The answer is 252.
The sequence is a list of numbers where each number is the sum of the previous two numbers. So, the first number is 2, the second number is 12 (2 + 10), the third number is 36 (12 + 24), the fourth number is 80 (36 + 44), and the fifth number is 150 (80 + 70). The sixth number in the sequence is 252 (150 + 102).
Option A, 194, is not in the sequence because it is not the sum of the two previous numbers. Option B, 210, is not in the sequence because it is not the sum of the two previous numbers. Option C, 252, is in the sequence because it is the sum of the two previous numbers. Option D, 258, is not in the sequence because it is not the sum of the two previous numbers.
