Question

If t1 = 5 and tn = tn-1 + 2, find the first 4 terms of the sequence.

Answer 1

\[t_2=t_1+2\]
so \[t_3=t_2+2\]
and \[t_4=t_3+2\]
just calculate t\2 cuz you know t_1.....

Answer 2

IAM CONFUSED

Answer 3

I'll do the first one kk ?!

Answer 4

to compute t_2 I'll take n=2 an see what I'll get
\[t_2=t_{2-1}+2=t_1+2\] as I know t_1=1 so t_2=1+2=3
did you understand .?

Answer 5

sorry t_1=5 ! so t_2=5+2=7

Answer 6

can you do the same for the rest ?!

Answer 7

I THINK SO

Answer 8

so do it ! I can check ! kk ?

Answer 9

IM SORRY I STILL DONT UNDERSTAND I THINK I REALLY DONT UNDERSTAND WHAT THE QUESTION IS ASKING ME WHAT AM I SUPPOSED TO DO EXACTLY LIKE WHAT IS THE QUESTION ASKING ME

Answer 10

THis is something called a recursive function. Plug in values for n.
\[t_4 = t_3 + 2\]\[t_3 = t_2 + 2\]\[t_2 = t_1 + 2\]\[t_1 = 5\]You have \(t_1\) = 5, so just plug that into the above function.
\[t_2 = t_1 + 2 \implies t_2 = 5 + 2 \implies t_2 = 7\]Can you do the same for the rest that's above?

Answer 11

SO IM FINDING WHAT THE OTHERS MEAN

Answer 12

Yes. If you realize, each of the functions include the value from before. So if \(t_2\) = 7, then plug it into \(t_3 = t_2 + 2\)and do the same again using \(t_3\) and you'll have you're answer :)

Answer 13

SO THAT WILL GIVE ME 4 TERMS RIGHT

Answer 14

Yes. 5 is one and 7 is another one like I said. Can you figure out the other 2?

Answer 15

YES THANK YOU VERY MUCH YU EXPLAINED IT SO I WOULD UNDERSTAND IT

Answer 16
