To find the 10th term of the given sequence where the first term is 7 and the sequence increases by , we can use the following formula:

=+d×(n−1)

where

represents the nth term of the sequence,

represents the first term of the sequence (7),

d represents the common difference between the terms (),

and n represents the term number we want to find (10).

 

Substituting the values into the formula, we have:

Simplifying inside the parentheses:
