how u solve this qus​

Answer 1

The answer is 248

Explanation

the difference among these terms are 1,3,7,15,31,63

Now the difference between the above terms are 2,4,8,16,32

You can clearly see that the next. No is the the double of the previous so the no which will come after 32 is 64

Now add this 64 to 63 the previous last no. The no. Now obtaines the the double of the previous so the no which will come after 32 is 64

Now add this 64 to 63= 127. we will get the answer as 121+127= 248

please mark it as the brainliest one

Answer 2

Step-by-step explanation:

as the third line is in GP series

so, z=64(by applying GP series formula)

now, if z=64

then, y=63+64=127

now, if y=127

then, x=121+127=248
