Answer:
Step-by-step explanation:
The nth term of the sequence is
To get the first term, substitute n=1,
To get the second term, substitute n=2,
To get the third term, substitute n=3,
The sum of the first three terms is
We could also use the formula
to get the same result.
Answer:
The table in the attached figure
Step-by-step explanation:
The picture of the question in the attached figure N 1
we have
Substitute the different values of x in the linear equation, to obtain the different values of y in the table
For x=-2 --->
For x=-1 --->
For x=-0 --->
For x=1 --->
The table in the attached figure N 2
The least number should always start off with negatives if there are any. In this case there is so we can start with -2 as our least amount. Next are the small fractions. If you're allowed a calculator, I would use that to find what the decimals will look like for each fraction:
After -2 the next least number is 0 and the next one is the fraction or decimal closest to the number 0 which is 0.4
The next number would be from the fractions we solved earlier. 0.5 and 0.625 would follow 0.4 and then 1.1 and 1.6667(solved for from fraction).
Here is the list:
