Question

how many even number are present up to 1000 find their sum​

Answer 1

Step-by-step explanation:

so in mathematical statement you can say that:

the question is:

=0+2+4+6+……….+998+1000

taking 2 common

=2(1+2+3+……….+499+500)

so as bracket has the sum of the 1st 500 natural numbers

As we have know the sum of natural numbers to n the formula is

S={n(n+1)}/2 where n is the number of terms hence

=2[{(500)(500+1)}/2]

=2{(250)(501)}

=2(125250)

=250,500 Answer.

Answer 2

Answer:

so in mathematical statement you can say that:

so in mathematical statement you can say that:the question is:

so in mathematical statement you can say that:the question is:=0+2+4+6+……….+998+1000

so in mathematical statement you can say that:the question is:=0+2+4+6+……….+998+1000taking 2 common

so in mathematical statement you can say that:the question is:=0+2+4+6+……….+998+1000taking 2 common=2(1+2+3+……….+499+500)

so in mathematical statement you can say that:the question is:=0+2+4+6+……….+998+1000taking 2 common=2(1+2+3+……….+499+500)so as bracket has the sum of the 1st 500 natural numbers
