The objective is to state why the value of
converging alternating seies with terms that are non increasing in magnitude
lie between any two consecutive terms of partial sums.
Let alternating series
<span>Sn = partial sum of the series up to n terms</span>
{S2k} = sequence of partial sum of even terms
{S2k+1} = sequence of partial sum of odd terms
As the magnitude of the terms in the
alternating series are non-increasing in magnitude, sequence {S2k} is bounded
above by S1 and sequence {S2k+1} is bounded by S2. So, l lies between S1 and
S2.
In the similar war, if first two terms of the
series are deleted, then l lies in between S3 and S4 and so on.
Hence, the value of converging alternating
series with terms that are non-increasing in magnitude lies between any two
consecutive terms of partial sums. So, the remainder Rn = S – Sn alternating
sign

Answer:
2x-9
Step-by-step explanation:
a number=x
multiply by 2
2x
subtracted by 9
2x-9
702 is your answer trust I can be lazy too
See the picture above for the solution.
Well, if a minute is 60 seconds, and she typed 10 words in 15 seconds, we can easily calculate the words per minute. Since 15 * 4 = 60, we need to do the same with 10. Ten * 4 = 40, so she cannot enter the typing contest. I hope this helps you.
