1 + 3 + 5 = 3 x 3 = 9
1 + 3 + 5 + 7 = 4 x 4 = 16
1 + 3 + 5 + 7 + 9 = 5 x 5 = 25


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

Answer:

100

Step-by-step explanation:

1+3+5+7+9+11+13+15+17+19=10*10

Answer 2

Answer:

1 is the first odd number , so 1×1

3 is the second odd number so 2×2

and it so continues...

therefore 19 is the 10th odd number , so the answer will be 10×10 = 100
