Which is the function describe the arithmetic sequence shown ? 3,7,11,15,19,23

Solution:

Given arithmetic sequence is:

3, 7, 11, 15, 19, 23

The nth term of arithmetic sequence is given as:

Where,

n is the nth term

d is the common difference between terms

is the first term of sequence

From given,

3, 7, 11, 15, 19, 23

Common difference, d = 7 - 3 = 4

Substituting the values in formula,

Where, n is positive integer,

Thus the function that describes the arithmetic sequence is found
