Answer:

Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
=
[ 2a₁ + (n - 1)d ]
where a₁ is the initial value and d the common difference
Given
=
[ 10 + (n - 1)3 ]
Then by comparison
2a₁ = 10 ( divide both sides by 2 )
a₁ = 4 ← initial value
and d = 3 ← common difference
Thus
=
[ 10 + (7 × 3) ]
= 4(10 + 21)
= 4 × 31
= 124
The equation of the line is
Explanation:
Given that the line passes through the points (-5,-3)
The slope of the line is
We need to determine the equation of the line.
<u>Equation of the line:</u>
The equation of the line can be determined using the formula,
Let us substitute the points (-5,-3) and the slope in the above formula.
Thus, we have;
Simplifying, we get;
Subtracting 3 from both sides of the equation, we get;
Hence, the equation of the line in slope - intercept form is
