To find out if the triangle is a right triangle, we must check if the following equation is true:
on the left side, we have:
and on the right side, we have:
since on both sides we get 625, we have that the brace forms a right triangle.

Solutions
We are given<span> the Arithmetic sequence -
A1,A2,A3,A4
</span>28,33,38,43
As we know the common difference can be found by subtracting the first term from the second term.
33 - 28 = 5 ((the common difference (d) = 5))
The variable n = the term you want to find which is = 11
d = difference = 5
