Question

What should come in place of the question mark (?) in the given series? 10, 22, 46, 94, 190, ?

• A. 385
• B. 389
• C. 387
• D. 382

Answer 1

Answer:

D. 382

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
