Answer:
47,643
Step-by-step explanation:
This question is basically asking you to add up all of these numbers together and present the end result.
1) 40,000 + 7,000 = 47,000
2) 600 + 40 + 3 = 643
3) 47,000 + 643 = 47,643.

thanks for the free points
Step-by-step explanation:
First we find the common difference...to do this we subtract the first term from the second term. -7 - (-1) = -7 + 1 = -6
now we are going to find the 10th term
an = a1 + (n-1)*d <== formula for finding any term in arithmetic series
a1 = 1st term, d = common difference, n = term we want to find
now we sub
a10 = -1 + (10 -1) * -6
a10 = -1 + (9 * -6)
a10 = -1 - 54
a10 = - 55
now we will find the sum
Sn = (n (a1+ an)) / 2 <== formula for finding the sum
S10 = (10(-1 - 55))/2
S10 = (10(-56) / 2
S10 = -560/2
S10 = - 280
so the sum of the first 10 numbers is -280
Answer:
{−1008,−504,−252,−126,…}
Step-by-step explanation:
-504÷(-1 008)=0.5
(-252)÷(-504)=0.5
(-126)÷(-252)=0.5
In this sequence ,we multiply by 0.5 each time to get the next term
then it’s a geometric sequence.
To do this, you can just multiply across. 3 times 1 equals 3 so your numerator is 3. 2 times 4 equals 8. Then, your answer would be 3/8. Hope this helps :)
