Question

The set builder form of (1,5, 9, 13, 17)
is
(1) {x:x = 2n+1, n € 2,0<n<4}
(2) {x:x = 4n+1, n € 2,05n54}
(3) {x:X = 4n+1, n € 1,05n54}
(4) {x:x = 4n+1, n € W,05n<2}​

Answer 1

A={1,4,9,16,25,}

We know that,

1,2,3,4,5,are the natural numbers.

And 1,4,9,16,25are the squares of this numbers.
