Rememeber that if a triangle is right, it satisisfies the Pythagorean Theorem. The Pythagorean Theorem is the following:

a^2 + b^2 = c^2

and

are the lengths of the legs of the right triangle

is the hypotenuse of the right triangle

Let's check to see if our side lengths work by "plugging them in," or inserting them into the expression:

$4^2 + 7^2 \stackrel{?}{=} 10^2$

$16 + 49 \stackrel{?}{=} 100$

$65 \neq 100$

The side lengths do not satisfy the Pythagorean Theorem, which means that the triangle is not right.

Step-by-step explanation:

It is going to be arithmetical sequence, a1=6

d=3, n=18

Sn= (2a1+d(n-1))/2*n= (2*6+3*17)/2*18= 63*9=567
