Write the set `{(1)/(2),(2)/(3),(3)/(4),(4)/(5),(5)/(6),(6)/(7)}` in the set-builder form.

Write {3,6,9,12} in the set -builder form ?

(i) Write sum_(r=1)^(n)(r^(2)+2) in expanded form. (ii) Write the series (1)/(3)+(2)/(4)+(3)/(5)+(4)/(6)+"…"+(n)/(n+2) in sigma form.

Write the set builder form A= {-1,1}

If A=[((2)/(3), 1,(5)/(3)),((1)/(3), (2)/(3), (4)/(3)),((7)/(3), 2, (2)/(3))] and B=[((2)/(5), (3)/(5), 1),((1)/(5), (2)/(5), (4)/(5)),((7)/(5),(6)/(5),(2)/(5))] , then compute 3A-5B .

Write the set builder form of A = {-1,1}

Write the interval (-3,0) in set builder form ?

The Cartesian equation of a line is (x-5)/(3)=(y-4)/(7)=(z-6)/(2) . Write its vector form.

If A and B be two sets and AxxB={(3,3),(3,4),(5,2),(5,4)} , find A and B.

Represent in set builder form {1,5,10,15……….}
