q(5)

no is not arithmetic progressing because the commons different the term not same

for AP common different
must be same between consecutive term

q(4)
sum of the root -b/a
= (-4/3)/1
=4/3
products of root c/a
9/1

9

q(6)
given x=a and y=b
give equation x-y=2
x+y=4 (equation 2)

equation 1and 2 add

x - y=2
x +y=4
................
2x=6. (y cancelled)
y=0
x=6/2
x=3
but a=x implied a=3 subtituting X-y=2
x-y=2
3-y=3
y=3-2=1


a=3. and b=1
