Answer:
6
Step-by-step explanation:
Let . We know the formula for the sum of an arithmetic sequence is:
Where n is the number term you are finding the sum up to, a1 is the first term, and an is the nth term. We can substitute what we have:
The formula to find the nth term of an arithmetic series is:
Where d is the common difference. Again, we can plug in what we have;
<span>the magnitude of a real number without regard to its sign.</span>
4x-6= x+6
4x= x + 12
5x= 12
X= 12/5
X= 2.5
Answer:
40.5 is what they are divided
