Question

write A={1,5,10,17,26} in Set builder form.explian

Answer 1

A = { 1 , 5 , 10, 17 , 26 }

let any number P = n^2 +1
where 0≤ n ≤5 and n≠ 1

n = 0 then , P = 1
n =2 then , P = 5
n =3 then, P =10
n = 4 then P = 17
n = 5 then P = 26

so, this satisfied above set .
now A = { 1 , 5 , 10, 17, 26 } in set builder form ----

A = { P :P = n^2 +1 where 0≤ n ≤5 but n≠1}
