Write an equation fo nth term of the given arithmetic sequence 7,13,19,25,...

The nth term for the given sequence can be written as:

Step-by-step explanation:

Notice that this arithmetic sequence is created by adding to each term a common difference of 6 units:

7 + 6 = 13

13 + 6 = 19

19 + 6 = 25

Then, using the general expression for the nth term of an arithmetic sequence of first term ""  and common difference "d" we can write the nth term as:

which in this case translates as:

Step-by-step explanation:

7,  13,  19,   25, .......

Arithmetic sequence.

First term = a = 7

Common difference = d = second term -  first term

            d = 13 - 7 = 6

nth term
