Let (a,) and (bn) be sequences in R and define c, as follows: For each natural number n, let c, = 5a, + 2b,. If (a,)is %3D convergent: Select one: O a. and (b,) converges to 0, then (c,-5a,) is eventually a constant sequence. O b. then (b,) is bounded if and only if (c,) is bounded. O c. none of the listed statements is true. O d. then sup(S)= inf(S') where Ss' is the set of subsequential limits of (a,).

Let (a,) and (bn) be sequences in R and define c, as follows: For each natural number n, let c, = 5a, + 2bn. If (a,)is
convergent:
Select one:
O a. and (b,) converges to 0, then (c,-5a,) is eventually a constant sequence.
O b. then (b,) is bounded if and only if (c,) is bounded.
O c. none of the listed statements is true.
O d. then sup (S)= inf(S') where s' is the set of subsequential limits of (a,).
