Answer 1

Answer:

Its very simple arithmatic formulasay you need to add 1, 2, 3, ….. upto “n” ….

Its very simple arithmatic formulasay you need to add 1, 2, 3, ….. upto “n” ….where n can be any integer, in this case say n = 9.

Its very simple arithmatic formulasay you need to add 1, 2, 3, ….. upto “n” ….where n can be any integer, in this case say n = 9.now we need to add the series 1+2+3+4+…….+9

Its very simple arithmatic formulasay you need to add 1, 2, 3, ….. upto “n” ….where n can be any integer, in this case say n = 9.now we need to add the series 1+2+3+4+…….+9then the formula is

Its very simple arithmatic formulasay you need to add 1, 2, 3, ….. upto “n” ….where n can be any integer, in this case say n = 9.now we need to add the series 1+2+3+4+…….+9then the formula isSum of the series = {n X (n+1)} / 2

Its very simple arithmatic formulasay you need to add 1, 2, 3, ….. upto “n” ….where n can be any integer, in this case say n = 9.now we need to add the series 1+2+3+4+…….+9then the formula isSum of the series = {n X (n+1)} / 2in our question n = 9

Its very simple arithmatic formulasay you need to add 1, 2, 3, ….. upto “n” ….where n can be any integer, in this case say n = 9.now we need to add the series 1+2+3+4+…….+9then the formula isSum of the series = {n X (n+1)} / 2in our question n = 9So the sum is 10 X (9+1) / 2= (10 X 10) /2 = 5 X 10 = 50 is the answer.
