Write an expression to describe the sequence below. use n to represent the position of a term in the sequence, where n = 1 for the first term. -1, 0, 1, 2,

is an expression which describe the given sequence

Step-by-step explanation:

Arithmetic sequence states that a sequence where the difference between each successive pair of terms is the same.  

The general rule for the arithmetic sequence is given by;  

              ......[1]

where

represents  the first term

d represents the common difference

and n is the number of terms;

Given sequence: -1 , 0 , 1 , 2 , .....

This is an arithmetic sequence with common difference

Since,

0-(-1) = 1

1-0 =1

2-1 = 1 ....

Here,

Substitute the value of , d =1 in [1] we get

Therefore,an expression which describe the given sequence is,  

nope
