A385

B389

C387

D382

Answer:

D. 382

Read Explanation:

Series:
10, 22, 46, 94, 190, ?

Find the differences between consecutive terms:

  • 22 − 10 = 12

  • 46 − 22 = 24

  • 94 − 46 = 48

  • 190 − 94 = 96

Now observe the pattern in differences:

  • 12, 24, 48, 96 → each time × 2

So the next difference will be:

  • 96 × 2 = 192

Add this to the last term:

  • 190 + 192 = 382
