The sum would be written as:
It goes from n=1 to =5 because it is the first 5 terms of the sum.
The sequence has a first term, a₁, of 1. The common difference, d, is 3. The explicit formula would then be:
Using the distributive property to simplify, we would have:
X^2 + x - 2 + 2x - 4....combine like terms
x^2 + 3x - 6 <=
Use the Pythagorean theorem<span> to calculate the value of X. Round your answer to the nearest hundredth. Remember our steps for how to use this </span>theorem<span>. This </span>problems<span> is like example 2 because we are </span>solving<span> for one of the legs. Identify the legs of the right triangle.

Also, since it's a math class there will be a bias.
Better method would be randomly selecting students from the entire school students list and take their feedback
