We know that
a1=1
a2=3
a3=9
a2/a1=3/1----> 3
a3/a2=9/3----> 3
<span>common ration r is equal to 3
number of terms n is 12
The </span><span>Sum of geometric series is given by the formula
</span>Sum=a1*[1-r<span>^n]/[1-r]
</span>Sum=1*[1-3^12]/[1-3]-----> Sum=[1-3^12]/[1-3]----> [3^12-1]/[3-1]
<span>Sum=531440/2-----> 265720
the answer is
265720

Answer:
144 goes with 12, 36 goes with 6, 9 goes with 3, and 121 goes with 11.
Step-by-step explanation:
The second number stated in each phrase is time itself to create the first number. For example, 144. If we take the second number in the number phrase (12) and time it by itself (12 * 12) it equals 144. This applies to each number phrase.
Answer:
Hi there!
Your answer is;
17/6 <em><u>OR</u></em> 2 & 5/6
Step-by-step explanation:
(-5+1)/6 - (-8+1)/2
First, simplify in parentheses!
-4/6 - -7/2
Next, change the symbol of 7/2 because two negatives make a positive!
-4/6 +7/2
Next, change the denominators so they both have the same
-4/6 + 7/2
× 3/3
-4/6 + 21/6
Simplify!
17/6
<u>OR</u>
2 & 5/6
Hope this helps
