an = a+(n-1)d
here a = 3
d = 1-3 = -2
an=3-2n+2
=1-2n
here a = 3
d = 1-3 = -2
an=3-2n+2
=1-2n

Ohh sry
It is 5
its okay
can you tell me this
wait I will send you
the length of the rectangle is 5 more than its breadth write the quadratic equation and find the perimeter of rectangle
Ok
Let the length be x
So that breath = 5+x
Perimeter of rectangle =2(l+b)
=2(x+x+5)
=2(2x+5)
=4x^2+10 i suppose
