Question

Suppose that lim n->infinity.....

Answer 1

\[\lim_{n \rightarrow \infty} a _{n} =4 \]
and
\[\lim_{n \rightarrow \infty} b _{n} =7 \]

Determine
\[\lim_{n \rightarrow \infty} (a _{n}+b _{n})\]

Answer 2

11

Answer 3

how?

Answer 4

11? lol. its simple.

Answer 5

oh JUUST KIDDING LOL

Answer 6

I put the wrong equation!

Answer 7

........

Answer 8

u cn break the bracket and apply limits individually if its a sum

Answer 9

\[\lim_{n \rightarrow \infty} a _{3}^{n}\]

Answer 10

still 4.

Answer 11

as n tends to infinity. infinity over 3 is still infinity.

Answer 12

what about \[\lim_{n \rightarrow \infty} 4b _{n}\]

Answer 13

28

Answer 14

yup.

Answer 15

\[4\lim_{n \rightarrow \infty}b _{n}= 4 x 7\]

Answer 16

okay last one ; \[\lim_{n \rightarrow \infty}(a _{n}^{2} - 2a _{n}b _{_{n}})\]

Answer 17

-40

Answer 18

4^2 - 2x4x7 = -40

Answer 19

yeah...

Answer 20
