plzzzzzz solve this

Answer 1

Where are the questions ?

Answer 2

if it is a sequence, then

in this sequence, multiples of 2 are increasing, then

in 1 and 5,there is a difference of 4 (2*2)

in 5 and 13, there is a difference of 8(2*2*2)

then as doing like this, a the difference between 61 and 125 is 64 (2*2*2*2*2*2)

then after that the difference between 125 and number after 125 should (64*2=128)

then the question mark will replace with 125 + 128=253


i hope this is right and will help you
