Answer:
30
Step-by-step explanation:
70-40=30
The ratio of the geometric sequence 40 is 2.
Given that geometric sequence is 40* and we have to find the common ratio of all the terms.
Geometric sequence is a sequence in which all the terms have a common ratio.
Nth termof a GP is a in which a is first term and r is common ratio.
Geometric sequence=40*
We have to first find the first term, second term and third term of a geometric progression.
First term=40*
=40*
=40*1
=40
Second term=40*
=40*
=40*2
=80
Third term=40*
=40*
=40*4
=160
Ratio of first two terms=80/40=2
Ratio of next two terms=160/80=2
Hence the common ratio of geometric sequence is 2.

Answer:
4/5 is the slope
Step-by-step explanation:
the formula is y=mx +b
m = slope
b= y intercept
Therefore, the slope in 4/5
