I'm doing a powerpoint for math, and one of the word problems involve arithmetic sequences. Can someone just type the "a sub n" and "a sub 1" "a sub 7" so that I can copy and paste onto my powerpoint? Or can you sow me how to find it? Thanks!
Sure, I can show you how to find the values of "a sub n", "a sub 1", and "a sub 7" for an arithmetic sequence.
In an arithmetic sequence, each term is found by adding a common difference to the previous term. The general formula for the nth term of an arithmetic sequence is:
a sub n = a sub 1 + (n - 1) * d
Here, "a sub n" represents the nth term, "a sub 1" represents the first term, and "d" represents the common difference.
To find "a sub n," you need to know the value of "n," the position of the term you want to find. For example, if you want to find the 10th term, then "n" would be 10.
To find "a sub 1," you can use the same formula, but with "n" as 1:
a sub 1 = a sub 1 + (1 - 1) * d
= a sub 1
The first term is equal to itself in an arithmetic sequence.
To find "a sub 7," you substitute 7 for "n" in the formula:
a sub 7 = a sub 1 + (7 - 1) * d
So, you'll need to know the value of "a sub 1" and the common difference "d" to find "a sub n," "a sub 1," and "a sub 7". If you provide me with those values, I can calculate and type them out for you, or you can enter them into the formula yourself.
