Answer:
-103
Step-by-step explanation:
So we have the sequence:
14, 11, 8, 5...
First, note that this is an arithmetic sequence because there is a common difference.
Each subsequent term is three less than the previous term.
To find the 40th term, we can write an explicit formula.
The standard form for an explicit formula for an arithmetic sequence is:
Where a is the initial term, d is the common difference, and n is the nth term.
We know that the initial term is 14. The common difference is -3 because each term is <em>minus</em> 3 the previous one.
Substitute in a and d:
We want to find the 40th term. So, substitute 40 for n:
Subtract:
Multiply:
Subtract:
So, the 40th term is -103.
