1. Correct Answer
     ● Option B: 252  
 2. Explanation
         ○ To find the value of X in the sequence, observe the pattern in the differences between consecutive terms:
           ○ Difference between 12 and 2: *10*
           ○ Difference between 36 and 12: *24*
           ○ Difference between 80 and 36: *44*
           ○ Difference between 150 and 80: *70*
         ○ The differences themselves form a sequence: 10, 24, 44, 70.
         ○ The differences between these differences are:
           ○ 24 - 10 = *14*
           ○ 44 - 24 = *20*
           ○ 70 - 44 = *26*
         ○ The second-level differences are increasing by 6: 14, 20, 26.
         ○ The next difference should be 26 + 6 = *32*.
         ○ Add this to the last difference: 70 + 32 = *102*.
         ○ Add 102 to the last term in the sequence: 150 + 102 = 252.
         ○ Therefore, the value of X is 252.
