PATTERN RULE →-2n +3
1. Create a table of values based on the above pattern rule (5
terms)
2. What is the value of the 20th term? The 50th term? 3. What term number has a value of (-69)?
1. Table of values:
n Value
1 1
2 1
3 -1
4 -3
5 -5
2.
To find the value of the 20th term, plug in n = 20 into the pattern rule:
-2(20) + 3 = -40 + 3 = -37
To find the value of the 50th term, plug in n = 50 into the pattern rule:
-2(50) + 3 = -100 + 3 = -97
3.
To find the term number that has a value of -69, we need to solve for n in the equation:
-2n + 3 = -69
-2n = -72
n = 36
Therefore, the term number that has a value of -69 is the 36th term.
