Sample Response: Both are correct. As long as inverse operations and the properties of equality are used properly, both methods will generate the same solution. They both isolate the variable on one side of the equation.
For an explicit formula in its simplified form, we must evaluate the first two terms.
For
,
, and
. We see that the common difference is
, and
, so we write,
.
The correct answer is
B.
Answer:
The number is 30
Step-by-step explanation:
