the smallest set such that A u (1 2 3 5 8) is.

$\huge{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

A ∪ {1, 2} = {1, 2, 3, 5, 9}

The elements of A and {1, 2} together give us the result.

Therefore smallest set of A can be.

A = {1, 2, 3, 5, 9} – {1, 2}

A = {3, 5, 9}
