Answer:
a is an element of A; a is a rational number
(a+1) is element of B
Step-by-step explanation:
(a+1) = sup(A), which are the elements of B.
(a+1) + 1 = sup(B)
Recall a+1 = sup(A),
Therefore,
sup(A )+ 1 = sup(B)
sup(B) = sup(A) + 1 ___proved
Sup(A) means supremum of set A. It means least element of another set (say set B), that is greater than every element in set A
