What should come in place of the question mark '?' in the following number series? 14, 26, 50, 98, 194, ?
386
Check how each term is obtained from the previous one.
14 × 2 − 2 = 26; 26 × 2 − 2 = 50; 50 × 2 − 2 = 98; 98 × 2 − 2 = 194.
So the rule is: multiply by 2 and subtract 2.
Next term = 194 × 2 − 2 = 388 − 2 = 386.
Hence, the missing number is 386.
