If 8,x,y,-4 is an arithmetic progression, find x and y
Answered by oobleck
there are three terms from the first to the last, so
3d = -4-8 = -12
now you can find d, and add it to find the missing terms.

Answered by Mauritha Joseph
a+(n-1)d = -4
8+(4-1)d = -4
8+3d = -4
3d = -4-8
3d = -12
Divide both sides by 3
3d/3 = -12/3
d = -4
x = a+d
= 8+(-4
x = 4
y = a+2d
= 8+2(-4)
= 8-8
y = 0
Therefore; x is 4 and y is 0
