Question

Express 64 and 121 as the sum of first n odd numbers​

Answer 1

Answer:

64= 1+3+5+7+9+11+13+15

because 64 is the square of 8

therefore, we had written first 8 odd numbers.

same here:

121= 1+3+5+7+9+11+13+15+17+19+21

because 121 is the square of 11

and we had taken first 11 odd numbers
