12, 4, 4/3, 16/3...
1/2, -1/2, -3/2, -5/2 ...
1/2, -1/2, 1/2, -1/2 ...
Answer:
The third sequence.
Step-by-step explanation:
In an arithmetic sequence, the difference between two consecutive terms is the same.
For each option, find the difference between consecutive terms:
First option:
The differences are not the same. As a result, this option is not an arithmetic sequence.
Second option:
The differences are not the same. As a result, this option is not an arithmetic sequence, either.
Third option:
The differences are all . As a result, this option is indeed an arithmetic sequence. Its common difference is
.
Fourth option:
The differences are varying between and
. As a result, this option is not an arithmetic sequence.
Answer: Number 3. (1/2, -1/2, -3/2, -5/2 ...)
Step-by-step explanation:
1/2 - 1 = -1/2. -1/2 - 1 = -3/2. Etc.
B. 1.63
C. 1.602
D. 1.603
its B because the 2 is in the hundredths place and then you look behind the 2 which is a 5. If its five or more you go up and 4 or less you go down. Which means that you add one to the 2 which is 3 and you get rid of anything behind the 3 that was the originally .
1.625 rounded to the nearesthundredth is 1.63.
Option B is the correct answer.
We have,
In this case, we look at the digit in the thousandth place (the third decimal place). If that digit is 5 or greater, we round up the digit in the hundredth place (the second decimal place). If it is less than 5, we leave the digit in the hundredth place as it is.
Now,
When rounding to the nearesthundredth, we look at the digit in the thousandth place, which is 5 in this case.
Since 5 is greater than or equal to 5 (half of 10), we round up the digit in the hundredth place, which is 2.
Therefore,
1.625 rounded to the nearesthundredth is 1.63.
