To find the terms of the arithmetic sequence given by the formula \( A(n) = -3 + (n - 1)(-2.2) \), we can substitute \( n \) with the desired term numbers.
-
First term \( A(1) \): \[ A(1) = -3 + (1 - 1)(-2.2) = -3 + 0 \cdot (-2.2) = -3 \]
-
Fourth term \( A(4) \): \[ A(4) = -3 + (4 - 1)(-2.2) = -3 + 3 \cdot (-2.2) = -3 - 6.6 = -9.6 \]
-
Tenth term \( A(10) \): \[ A(10) = -3 + (10 - 1)(-2.2) = -3 + 9 \cdot (-2.2) = -3 - 19.8 = -22.8 \]
Now we have the first, fourth, and tenth terms of the sequence:
- First term \( A(1) = -3 \)
- Fourth term \( A(4) = -9.6 \)
- Tenth term \( A(10) = -22.8 \)
