**Answer : 55**

The series ā1+2+3+4+5+6+7+8+9+10ā can be considered as the sum of the first 10 Natural numbers.

The generalized formula to find the sum of first N natural numbers is

(N * (N + 1) ) /2

For the series given, the value of N is 10

So substituting value of N in the generalized formula

( 10 * (10 + 1) ) / 2

= (10 * 11 ) / 2

= 110/2

Correct answer = 55
