Question

What should come in place of the question mark (?) in the given series? 878 880 884 890 898 ?

• A. 904
• B. 906
• C. 908
• D. 910

Answer 1

Answer:

C. 908

Series:
878, 880, 884, 890, 898, ?

Find the differences:

• 880 − 878 = 2

• 884 − 880 = 4

• 890 − 884 = 6

• 898 − 890 = 8

The differences are increasing by +2 each time.

So next difference = 10

Next term = 898 + 10 = 908
