A series is given with one term missing. Choose the correct alternative from the given ones that will complete the series.
130, 450, 970, 1690, ?

Let us look at the differences between the consecutive terms of the given progression:
450−130=320

970−450=520

1690−970=720

Now, analyze the pattern of the differences:

520−320=200

720−520=200

The difference increases uniformly by 200 each step. Thus, the next difference value should be:

720+200=920
Adding this difference value to the final listed term of the sequence:

Missing term=1690+920=2610
