1-
156 lies between 144 and 169
So
lies between 12 and 13.
2- 
320 lies between 289 and 324.
So
lies between 17 and 18.
3- 
249 lies between 225 and 256
So
lies between 15 and 16.
If the sequence is -4,-8,-16,.. then the seventh term be -256.
Given a sequence be -4,-8,-16,...
We are required to find the seventh term of the sequence.
If we carefully observe the sequence then we will find that the sequence is a geometric progression.
Geometric progression is a sequence which has a common ratio between all the terms.
Ratio of 2nd and 3rd term=-8/-4=2
Ratio of 3rd and 2nd term=-16/-8=2
Because the ratio is equal, so the sequence will be called a geometric progression.
Nth term of G.P=a
7th term=-4*
=-4*64
=-256
Hence if the sequence is -4,-8,-16,.. then the seventh term be -256.

Answer:
x(6x-25y) is your answer ☺️☺️☺️
3/8<1/2
5/8>1/2
1/2 is .5
3/8 is .375
5/8 is .625
hope this helps
