B Correct answer
Explanation

The pattern is the difference between consecutive terms keeps halving: 158-126=32, 174-158=16, next difference should be 8, so P=174+8=182. Continuing: 186-182=4, 188-186=2. The differences 32,16,8,4,2 form a geometric progression with ratio 1/2. Option B (182) is correct.
