What should come in place of the question mark (?) in the following number series?
56, 54, 58, 50, 66, ?
Let the missing number be x
Here , a pattern is getting formed between consecutive numbers.
54−56 =$$(-2)^1$$
58−54= $$(-2)^2$$
50−58= $$(-2)^3$$
66−50= $$(-2)^4$$
As we can see that the difference is of the form $$(-2)^{n}$$
so for missing number x,
x−66= $$(-2)^{5}$$
This implies that x is 34
