Question

write the first 5 terms of the sequence? A sub 1= 10, A sub (n -1) -5

Answer 1

I am really confused

Answer 2

did you type everything correctly?

Answer 3

I cant type the subscripts so it doesn't look the same exactly

Answer 4

\[a _{1}^{}= 10, a _{n-1}^{}-5\]
that is correct

Answer 5

a 1 =10,an=a n−1 −5

Answer 6

What a difference that makes!

Answer 7

ok, that makes sense now.

Answer 8

okay Sorry lol

Answer 9

Substitute n = 2, you get a sub 2 = (a sub 1) - 5
= 10 - 5
= 5

Now, lets put in n = 3, so a sub 3 = (a sub 2) - 5
= 5-5
= 0

Now, lets out in n = 4, so a sub 4 = (a sub 3) - 5
= 0 - 5
= -5

Finally, n = 5, so a sub 5 = (a sub 4) - 5
= -5 - 5
= -10

So 5th term, a sub 5 = -10

Answer 10

okay thanks :) but you just sub in the a1 and so forth

Answer 11

Yes, you put in a sub 1 to find a sub 2. Then put in a sub 2 to get a sub 3, and so on. As I showed you step-by-step.
