Question

An+1=3a,-n, a,=2.... ...........​

Answer 1

Ответ:

а=2

2n+1=3×2

2n+1=6

2n=6-1

2n=5

n=5÷2

n=2,5

2×2,5+1=3×2

5+1=6

6=6

Answer 2

It seems like you're trying to define a sequence using a recurrence relation, but there might be a typo or some missing information in your expression. The notation you've used, "An+1=3a,-n, a,=2," is not standard and a bit confusing.

Typically, a recurrence relation is defined in the form:

$a_{n+1} = f(a_n)$

where $a_n$ represents the $n$th term of the sequence, and $f$ is some function that calculates the $(n+1)$th term based on the $n$th term.

If you could provide the correct recurrence relation or clarify the expression you've given, I'd be happy to help you further.
