Answer:
14, 7, 0, -7.
Explanation:
To find the first four terms of the sequence, we can substitute different values of n into the given expression and simplify.
The expression for the nth term of the sequence is 7(3 - n).
Let's find the value of the first term (n = 1):
T₁ = 7(3 - 1) = 7(2) = 14
The first term of the sequence is 14.
Now, let's find the value of the second term (n = 2):
T₂ = 7(3 - 2) = 7(1) = 7
The second term of the sequence is 7.
Next, let's find the value of the third term (n = 3):
T₃ = 7(3 - 3) = 7(0) = 0
The third term of the sequence is 0.
Finally, let's find the value of the fourth term (n = 4):
T₄ = 7(3 - 4) = 7(-1) = -7
The fourth term of the sequence is -7.
Therefore, the first four terms of the sequence are:
