This might take a while, but you just add up every odd number from 1 to 934. You know, 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, and so on.

There's an arithmetic equation for it im looking for.

OpenStudy (anonymous):

@johnny101 i this this may help you.... http://www.wikihow.com/Add-a-Sequence-of-Consecutive-Odd-Numbers

OpenStudy (anonymous):

else i will do it by converting it into simple Arithmetic progression problem

OpenStudy (anonymous):

where we know the first and last term and the difrnc too

OpenStudy (anonymous):

can u cover that?

OpenStudy (anonymous):

1+3+5+....934 terms a=1, d=3-1=2,n=934 \[S _{n}=\frac{ n }{ 2 }\left[ 2*a+\left( n-1 \right)d \right]\] \[calculate S _{n}\]

OpenStudy (anonymous):

that cant be right the answer is 870488?

OpenStudy (anonymous):

i solved for first 934 odd terms

OpenStudy (anonymous):

check your question.

OpenStudy (anonymous):

square it

OpenStudy (anonymous):

the sum of the first \(n\) odd numbers is \(n^2\)

OpenStudy (anonymous):

that is all you need to do the sum of the first 5 odd numbers is 25, the sum of the first 100 odd numbers is 10000, etc

OpenStudy (anonymous):

So 934/2= 467, 467x467= 218089 is the sum…?

OpenStudy (anonymous):

no

OpenStudy (anonymous):

there is no reason to divide by 2 the question asks How do i find the sum of the first 934 odd natural numbers? and the answer is \(934^2\)

OpenStudy (anonymous):

you sure?

OpenStudy (anonymous):

if you takesum of the first 10 25 not 100

OpenStudy (anonymous):

1+3+5+7+9= 25, 10 squared would be 100...
