Write an expression for the nth term of... 2,1,0,-1...

Mathematics
1 answer:
Drupady [299]3 years ago
7 0

Answer:

a_{n} = 3 - n

Step-by-step explanation:

There is a common difference between consecutive terms in the sequence, that is

1 - 2 = 0 - 1 = - 1 - 0 = - 1

This indicates the sequence is arithmetic with n th term

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 and d = - 1 , thus

a_{n} = 2 - 1(n - 1) = 2 - n + 1 = 3 - n

kirza4 [7]

Answer:

It's 1/2  I found this out by subtracting 3/4 - 1/3= 5/12 and if you put that into a decimal it would be .41. So that 1/4= .25 and 1/2= .50. You could figure out that it’s closed to 1/2.
