Question

113, 225, 449, ? , 1793

Answer 1

113*2-1=225
225*2-1=449
449*2-1=897
897*2-1=1793
Hence correct answer is 897

Answer 2

Answer:

897

Step-by-step explanation:

The missing number in the given sequence can be calculate as:

$113{\times}2-1=225$,

$225{\times}2-1=449$,

$449{\times}2-1=897$,

$897{\times}2-1=1793$

If we multiply the previous number with two and then subtracting one from the resulting answer, we get the next corresponding number, similarly by following this path, missing number can be easily calculated.

Hence, the missing  number will be: 897.
