We have
a2 = 4
a3 = 2
a4 = 1
calculate the
difference
a3 - a2 = -2
a4 - a3 = -1
The differences
are not equal---------- >the sequence is not arithmetic.
Getting the
ratio:
a3/a2 = 0.5
a4/a3 = 0.5
The common ratio
is 0.5. Using the general form for a geometric series:
an = a1 r^(n-1)
for n = 2----------------
> a2=4
4 = a1 (0.5)^(2-1)
a1 = 8
therefore
an = 8 (1/2)^(n-1)
the answer is an = 8 (1/2)^(n-1)
the answer is none of those indicated in the question
Answer:
y = -
Step-by-step explanation:
slope-intercept form : y = mx + b
Solve for y.
Subtract 3x on both sides. You get --> 7y = -3x - 14
Divide by 7 on both sides. You get --> y = 
Simplfy it. -14/7 = 2 so you get y = -

Hope it is helpful.....
STEP BY STEP EXPLANATION
(Mark brainliest pls)
Square root is 2 square + 4 square + 1 because 1 does not enable a square perhaps for negatives to be imputed, and we know 2 square will be 1 hence,
1 x 1 = 1 squared
2 x 2 = 4 squared
Perhaps for 1, you will have to use a formula equation and add tang maybe. Etc I don’t know if tang but u will also have to convert 1 to a decimal to find the square root of 1, 1 is an odd number so it will end up with remainder decimals or just do 1x1, etc.
Hence u
(2 square + 4 square) + 1square?
It depends on addition or order of operations subtraction addition or you will might use multiply
if the subject is about multiply or Division so try and do it because i don’t know if I’m right
..
REMEMBER
PEMDAS
Please Excuse My Dear Aunt Sally

try and solve it hope this helps!
