Question 27

Select the number from among the given options that can replace the question mark (?) in the following series.
834, 836, 844, 876, 1004, ?

Solution

$$834+2^1\ =\ 834+2\ =\ 836$$

$$836+2^3\ =\ 836+8\ =\ 844$$

$$844+2^5\ =\ 844+32\ =\ 876$$

$$876+2^7\ =\ 876+128\ =\ 1004$$

$$1004+2^9\ =\ 1004+512\ =\ 1516$$

Hence '1516' will come in place of the question mark.
