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.

The correct answer is: " 1/8 " .
__________________________________________________________
Note: "4/9" is close to "1/2" . Since "4/8 = 1/2" ; and since "4.5/9" = "1/2" .
"1/8" is a MUCH SMALLER value than "1/2" ;
and: "1/8" is a much smaller value than "4/9".
__________________________________________________________
Hence, " 1/8" is much closer to "0" than "4/9" .

The correct answer is: "1/8" .

Answer:
x= -5 and x= 3
Step-by-step explanation:
You have the factored equation, all you need is to switch the signs on the numbers and that is the answer.
Answer:
25. rational
26. irrational
Step-by-step explanation:
A rational number is a number that can be written as a fraction. It may have decimals that end or repeating decimals.
An irrational number cannot be written as a fraction. It's decimals continue on and do not repeat.
25.
When you multiply two rational numbers, the product is rational. The square root of 16 is 4, which is rational because it is a whole number. 4/7 is written as a fraction so it is rational.
26.
The square root of 2 is an irrational number because its decimals go on and do not repeat. 7 is a whole number so it is rational. Subtracting a irrational number from a rational number gives an irrational number.
