Is this an arithmetic sequence 1,1/2,1/4,1/8

Mathematics
1 answer:
valentinak56 [21]3 years ago

Answer:

No, it is a geometric sequence.

Step-by-step explanation:

The 2nd term is half the first term, the 3rd term is half the second term, etc..

If it were an arithmetic sequence you would need to add or subtract the same difference each term, but here you are multiplying each term by 1/2.

Please fill in the blanks between the numbers with correct math symbols 5_6_15_9=24
vekshin1

Answer:

5*6-15+9=24\\

Step-by-step explanation:

To try to solve these problems, you could plug 'n play. If all the blanks are addition, you/ll be > 24

If all the blanks are subtraction, it will be < 0

Multiplication doesn't work for all of them.

I did notice that 15 + 9 = 24, 5*6 = 30, and you get back to 15 if you subtract 15 after multiplying 5 and 6

What is the fifth term of the geometric sequence a1=120, a2=36, a3=10.8, a6=0.2916?
iragen [17]
First we need to find the common ratio by dividing the second term by the first term. 36/120 = 3/10

an = a1 * r^(n-1)
n = term to find = 5
a1 = first term = 120
r = common ratio = 3/10
now we sub and solve
a5 = 120 * 3/10^(5 - 1)
a5 = 120 * 3/10^4
a5 = 120 * .0081
a5 = 0.972 <=== fifth term

or we could have just done this......since we multiply by 3/10 to find the next number...
a3 = 10.8......10.8 * 3/10 = 3.24 <== 4th term
3.24 * 3/10 = 0.972 <== fifth term

Lunna [17]

Answer:

-2 7/6, -1 3/4, -1 1/2, 1/8

Step-by-step explanation:

The "greater" the number is when it's negative, the less value it actually holds. Therefore, -1 3/4 is less than -1 1/2!
