Find the first four terms of the sequence represented by the expression.
3n+5
A. 3,8,14,20
B. 8,11,14,17
C. 3,6,9,12
D. 0,8,11,14
Did you sub in n = 1, 2, 3, ...
Well the first one:
n = 1
then 3n+5 = 3(1)+5 = 8
I see only one choice that starts with 8
To find the first four terms of the sequence represented by the expression 3n+5, we substitute values for n and simplify the expression.
Let's substitute n = 1:
3(1) + 5 = 3 + 5 = 8
Now, let's substitute n = 2:
3(2) + 5 = 6 + 5 = 11
Next, let's substitute n = 3:
3(3) + 5 = 9 + 5 = 14
Finally, let's substitute n = 4:
3(4) + 5 = 12 + 5 = 17
Therefore, the first four terms of the sequence represented by the expression 3n+5 are 8, 11, 14, 17.
The correct answer is B. 8, 11, 14, 17.
To find the terms of the sequence represented by the expression 3n + 5, we need to substitute different values of n into the expression and evaluate it.
Let's substitute the first four positive integers (n = 1, 2, 3, 4) into the expression:
For n = 1: 3(1) + 5 = 8
For n = 2: 3(2) + 5 = 11
For n = 3: 3(3) + 5 = 14
For n = 4: 3(4) + 5 = 17
So, the first four terms of the sequence represented by the expression 3n + 5 are 8, 11, 14, 17.
Therefore, the correct answer is B. 8, 11, 14, 17.
