∑ 8(
)⁽ⁿ⁻¹⁾ from n = 1 to n = 5
n = 1 → 8()⁽¹⁻¹⁾
= 8 = 
n = 2 → 8()⁽²⁻¹⁾
= 
= 
n = 3 → 8()⁽³⁻¹⁾
= 
= 
n = 4 → 8()⁽⁴⁻¹⁾
= 
= 
n = 5 → 8()⁽⁵⁻¹⁾

The data set in discuss which contains three points and two of the residuals are 7 and -3 would have its third residual as; -4.
<h3>What is the third residual if the data set characterized as having 2 of its three residuals to be; 7 and -3?</h3>
According.tinthe task content, the data set in discuss has three points and consequently should have three residuals.
Additionally, two of the three residuals have been given and on this note, it follows that the third residual must have a value such that the algebraic sum of all residuals is 0.
Hence, we have; -3 + 7 +x = 0;
x = 3-7 = 4.
Ultimately, the third residual is; -4.

Distribute the ( ).....get -6y -10= -4
Add 10 on both sides, get -6y=6. Divide by-6, get y of -1
