Question

( x + 1 ) + ( ​x + 2 ) + ( x + 3 )+ .... + ( x + 100) = 5050.

Answer 1

(x+1) + (x+2) +....+(x+100) = 5050

100 x X + ((100+1) x 100 : 2) = 5050

100 x X + 5050 = 5050

100 x X = 0

=> x = 0         

Answer 2

(X+1)+(X+2)+(X+3)+...+(X+100)=5050

=>(X+X+X+...+X)+(1+2+3+...+100)=5050

=>100X+[(1+100)x100:2)]=5050

=>100X+(101x100:2)=5050

=>100X+(10100:2)=5050

=>100X+5050=5050

=>100X=5050-5050

=>100X=0

=>X=0:100

=>X=0
