Question 39
Which number will replace the question mark (?) in the following number series?
256, 123, 66, ?, 18, 6
Solution
Given Series,
256, 123, 66, ?, 18, 6
The pattern follows here is :
we see it from right hand side,
$$\therefore\ \left(6\times\ 2\right)+6=18$$
$$\therefore\ \left(18\times\ 2\right)-7=29$$
$$\therefore\ \left(29\times\ 2\right)+8=66$$
$$\therefore\ \left(66\times\ 2\right)-9=123$$
$$\therefore\ \left(123\times\ 2\right)+10=256$$
Hence, Option C is correct.
