1 2 3 4 .... 1002 what is the sum of the sequence

Reika [66]

<span>As far as i know it is related to Gauss.
Write the sequences forward and backward first.

1 +2 +3 +.....+1002
1002+1001+1000+.....+1
--------------------------------------... Adding them
1003+1003+......(1002 times)
=1002x1003
But this contains the series twice.
So, the sum is = 1002x1003/2=501x1003=502503. answer</span>

Jamal ran 8 kilometers, sprinted 500 meters, and climbed bleachers for a distance of 1.5 kilometers during track practice. How m

stiv31 [10]

Answer: $10,000\ meters$

Step-by-step explanation:

In order to calculate the total meters Jamal traveled during the practice, you need to make the conversions from kilometers to meters.

You need to remember that:

$1\ km=1,000\ m$

Therefore:

$(8\ km)(\frac{1,000\ m}{1\ km})=8,000\ m$

$(1.5\ km)(\frac{1,000\ m}{1\ km})=1,500\ m$

Finally, you can solve the following addition in order to get the total meters Jamal traveled during the practice. The sum is:

$total=8,000\ m+500\ m+1,500\ m\\\\total=10,000\ m$
