Question

Express. 81 as a sum of continous odd number starting from 1​

Answer 1

Answer:

1+3+5+7+9+11+13+15+17=81

Step-by-step explanation:

as we have read that the sum of n positive and continuous odd no's is n²

here sum of odd continuous integers is 81

so, n²=81

n=±9

here, -9 should be neglected because odd no. can't be negative

so no. of integers =9

so, no. are

1+3+5+7+9+11+13+15+17
