In each of the following questions, choose the correct alternative from the given ones that will complete the series.
30, 130, 630, ?
The series is 030,130,630
The first digit of each term is one more than five times the first digit of the previous term followed by 30.
130 = ((10$$\times$$ 5 +1) 30
630 = ((1 $$\times$$ 5 +1) 30
Hence the term after 630 = ((6 $$\times$$ 5) +1) 30 = 3130.
Hence Option B is the correct answer.
