The sum of the first n terms in a geometric sequence given the first term (a1) and the common ratio (r) is calculated through the equation,
<span>Sn </span>= (<span><span><span>a1</span>(1−<span>r^n</span>) / (</span><span>1−r)
Substituting the known terms,
Sn = (20)(1 - (1/4)^4)) / (1 - 1/4)
Sn = 26.5625
Thus, the sum of the first four terms is 26.5625. </span></span>
Answer:
Graph is not listed
Step-by-step explanation:
I believe the slope is 3/4
9-3 = 6
4 - (-4) = 8
Simplify to get 3/4
Answer:
(x-8) is the factor.
Step-by-step explanation:
The given trinomial is 
.
We need to find the factor of this trinomial.
The factors of is (x-2) and (x-8).
So, the factor of is (x-8). Hence, the correct option is (B).
