Question

whats a term sequence? like for the question...


Give the 5th and 10th term for the sequence formula below.
tn =


5, 10

5/4, 10/4

4/5, 2/5

4/5, 10/4

Answer 1

A term sequence is something of the nature:
1 2 3 4 5 etc
Where in this case each following number is the last one plus one.
So formally:
\[n_i = n_{i-1} + 1\]

Answer 2

I dont think I can see your sequence, so I cant help you with an anwer. Try to do it yourself, if you still cant copy the sequence here! :)

Answer 3

im so confused. lol. Whats the sequence im suppose to be copying?

Answer 4

You see in your question, you go "The formula below: Tn = " and then just a big blank haha. So I dont know what the formula is.

Answer 5

oh sorry about that here is the rest of the rest of the formula: tn = 4/n

Answer 6

well look at the formula. n stands for number of the term. so if you want term number 5 and 10, you replace n by that. You get 4/5 and 4/10

Or in other words, 4/5 and 2/5

Answer 7

but what if the equation is like this tn = (n – 3)2. And it still wants us to use 5 and 10. So i replace N with 5 and i have T5=(N-3)2. and now?

Answer 8

you forgot to replace the other n!

youll get T5 = (5-3)2 = 2*2 = 4

Answer 9

OH!

Answer 10

hope that helps :)

Answer 11

\[t_n = \frac{4}{n}\]

To find 5th and the 10th term,

In the above value of tn , put n= 5 once and n = 10.

\[t_5 = \frac{4}{5}\]

And now put n = 10

\[t_{10} = \frac{4}{10} = \frac{2}{5}\]

Answer 12

well soati, i got 9.8.... And waterineyes, a fraction isnt an answer choice...:)

Answer 13

What do you mean, you got 9.8?

Answer 14

What do you want to tell @razzy ??

Answer 15

ok so. T5=(10-3)squared . so 10-3=7. 7 times 7 is 49. that divded by 5 is 9.8

Answer 16

also waterineyes just wrote the exact same thing I did for the original question lol

Answer 17

waterineyes, i just wanted to say that from the answer choices, what you said isnt there. and thats not what i got either...

Answer 18

C is the option can't you see??

Answer 19

Wait I dont get it. If you want T5 you just replace N by 5 and get (5-3)^2
But if you want T10 replace N by 10 and get back (10-3)^2 = 49. Why did you divide by 5?

Answer 20

OH. I was solving it like this >>> T5=(10-3)squared.....i replaced both Ns.

Answer 21

@soati , I just gave the answer in more understandable form...

Answer 22

lol please.

anyway, do you get it now razzy?

Answer 23

waterineyes, we already got that answer... ok lemme try it again.

Answer 24

YES. I GET IT NOW. Thank you soati. You were loads of help!

Answer 25

anytime :)

Answer 26

ok wait. rofl im confused again. the first question you helped me with was the TN=4/N. And the answer was 4/5 and 2/5. but the question i asked you second, is tn = (n – 3)2... And when i do this, i get the same answer we got in the first problem! And its not an answer for the 2nd.

Answer 27

How so? What answers did you get? We just did both of them, and if Im not mistaken we got 4 for the 5th term and 49 for the 10th?

Answer 28

Oh. nvmmm. rofl. i was confused because no one really made it official what out answer was, and we were talking about question 1 when you were trying to teach me

Answer 29

ahah sorry. the question is getting pretty long yes.

So for problem one, 4/5 and 2/5.
Problem two, 4 and 49!

Answer 30

OK. So were on the same page now. xD

Answer 31

Let us try one more example @razzy ..

Let us try for,

tn = 4n + 5


NOTE: In tn, n is only the suffix it is nothing to do with calculation..

Only n that matters is n attached with digit 4..

So,

tn = 4n + 5

Find the 20th and 40th term of this Arithmetic Progression...

Answer 32

k. im trying it right now.

Answer 33

Okay, take your time...
