Math Problem Statement
Solution
From the image, the problem provides two terms of a sequence:
This likely refers to an arithmetic or geometric sequence, where we need to find further terms, the common difference (in arithmetic sequences), or the common ratio (in geometric sequences), or determine the formula for the sequence.
Let's first assume it's an arithmetic sequence, which follows the form: where is the -th term, is the first term, is the term number, and is the common difference.
We have two equations from the given terms:
We can solve these equations to find and . Let's proceed with that.
Step 1: Express in terms of from the first equation:
Step 2: Substitute into the second equation:
Step 3: Solve for : First, subtract 8 from both sides: Now, divide both sides by 3:
Step 4: Find : Substitute into :
So, the sequence is an arithmetic sequence with:
- First term
- Common difference
