1,3,7,15,31,__,____,__​

Answer 1

Answer:

63,127,255 is your answer

Answer 2

Answer:

63,127, 255

Step-by-step explanation:

Here the sequence is- 2n+1 where n is the number on which you are calculating

like for 1, 2n+1= 2(1)+1= 3

similarly for 3, 2n+1= 2(3)+1= 7

so,

31(2)+1= 63

63(2)+1= 127 and

127(2)+1= 255
