Question

What is the value of 1+3+5+7+........4033+7983 *2017?

Answer 1

Answer:

8,205,738,913

Step-by-step explanation:

1,3,5....4033 are in A.P

therefore first find the number of term

nth term=a + (n -1)d

4033=1 + (n-1)2

(4033 - 1/2) +1=n

n=2017

sum of n term =n/2(a+l)

l= last term =4033

=2017/2(1+4033)

=1008.5*4034

=4,068,289

therefor the value of 1+3+5+7...+4033*2017=4,068,289*2017

=8205 738 913
