Step-by-step explanation:
= - 4
= a* + (3- 1) d*
- 4 = a + 2d . . . . . . . . .(i)
= - 29
= a + ( 8 - 1) d
- 29 = a + 7d . . . . . . . . (ii)
subtracting equations (i) and (ii)
25 = 5d
d = -5
placing d = -5 in equation (i)
a - 10 = -4
a = 6
For an arithmetic Progtession
= a + (n - 1)d
= 6 + (n- 1)-5
= 6 - 5n + 5

Answer
<span>D) Any point on a perpendicular bisector is equidistant from each endpoint of the line segment.
Explanation.
A perpendicular bisector, divides the line segment in to two equal parts. It should be perpendicular to the line segment.
The best description the </span><span>the construction of a perpendicular bisector is the one that talks of a general points that lies along the perpendicular bisector and are equidistant from the two ends. From the choices the answer is; </span><span>Any point on a perpendicular bisector is equidistant from each endpoint of the line segment.</span>
The sum of a number and its additive inverse is equal to zero. E.g. an additive inverse of 2 is -2.
