Question

1+2+3+4....50 all plus which number find

​

Answer 1

Answer:

1275

Step-by-step explanation:

The series 1 to 50 ; 1, 2, 3….48, 49, 50 is an Arithmetic Progression (A.P.) with the series equally spaced with a gap of one.

Note :- In an A.P. series, if we are given the first and last term, then the formula to calculate the sum of the series is :-

N (a1 + al) / 2 where N is the number of terms in the series. a1 and al denotes the first term and last term of the series respectively.

Hence, by substituting the values for the given question in the above formula :- 50 (1+50) / 2 -> we get the result as 1275.

Answer 2

1+2+3+4+5+6+7+8+9+5 = 50
