Question

which expression defines the given series for seven terms?
-13 + (-16) + (-19) +...

help me pleaseee:)

Answer 1

T=-3n-10

Answer 2

thank youuuu!!:)

Answer 3

A{n+1} = A{n} - 3 ; A{0}= -13 defines the sequences; and I spose the sum of the functinal equation would define the series right?

Answer 4

He's more likely to be right than me take his answer instead
It depends what expression you normally use

Answer 5

is should prolly rewrite my recursion as:

\[A_{n}=A_{n-1}-3;A_0=-13\]

Answer 6

\[A_n = -13 -3n\]
perhaps?

Answer 7

yeah, that start at 1 or 0 can be rather indeterminate :)

Answer 8

I learnt it by starting at \[t _{1}\] with it being\[ t_{n}\]

Answer 9

But I remember the \[ A_{n+1}\] being another way of writing it
