Question

Select the number from the given options that can come next in the following series.
1, 12, 124, 1248, 12496, _______.

A.

124982

B.

124962

C.

124992

D.

124978

Correct option is C

Given:
​1, 12, 124, 1248, 12496, _______.
Logic: Here, twice the last of the numbers is added to the ten times the number to get the next term in the given series:
(1 × 10) + (2 × 1) = 10 + 2 = 12
(12 × 10) + (2 × 2) = 120 + 4 = 124
(124 × 10) + (2 × 4) = 1240 + 8 = 1248
(1248 × 10) + (2 × 8) = 12480 + 16 = 12496
(12496 × 10) + (2 × 16) = 124960 + 32 = 124992
Thus, '124992' is the next term in the given series.
