If N and A are defined, you multiply the value of N by the value of A.
<span>They are finite sums of expressions of the form where a is a constant, x is the variable and k is a non-negative integer</span>
1/3 because only 1 and 2 is less than 3 out of the 6 numbers. 2/6 = 1/3.
The explicit rule for any arithmetic sequence is:
a(n)=a+d(n-1), a=initial term, d=common difference, n=term number
In this case a=-3 and d=7 so:
a(n)=-3+7(n-1)
a(n)=-3+7n-7
a(n)=7n-10
An isosceles triangle is a triangle with 2 congruent sides. The congruent sides are called legs and the third side is called the base. So if 2 sides of a triangle have the same length, then we say that the triangle is isosceles.
