= 16 - 4(-14)
= 16 + 56
= 72
Discriminent is positive

Let first term be a and common difference be d.
pth term = a + (p-1)d = q -----(i)
qth term = a + (q-1)d = p -----(ii)
(ii) - (i) gives
(q - p)d = p - q or d = -1
(i) gives a = q - (p-1)d = q - (p-1)(-1) = q + p - 1
Hence,
nth term = a + (n-1)d
= q + p -1 + (n-1)(-1)
= q + p -1 + n +1
= p + q - n

Let the ages be x and y
x+y=20---------------(1)
4 years ago......
(x-4)(y-4)=48
xy-4x-4y-16=48
xy-4(x+y)=48+16
xy-4(20)=64
xy=144
x=144/y
substitute in (1)
x+y=20
144/y+y=20
144+y²=20y
y²-20y+144=0
which is impossible to be solved
so, it is impossible

Substitute the value of x ,
X+y=137
Y=137-90
