Which number will lie in place of $\star$ in the sequence: 8, 14, 26, 50, $\star$ ?
98
Differences between consecutive terms: 14-8=6, 26-14=12, 50-26=24. Each difference doubles the previous one (6, 12, 24, 48...). So the next difference is 48, giving the next term = 50 + 48 = 98. Hence option (B) is correct.
