Question

how many consecutive odd numbers will be needed to get the sum as 5 cube​

Answer 1

Sum of first odd number = 1.

Sum of first two odd numbers = 1 + 3 = 4 (4 = 2 x 2).

Sum of first three odd numbers = 1 + 3 + 5 = 9 (9 = 3 x 3).

Sum of first four odd numbers = 1 + 3 + 5 + 7 = 16 (16 = 4 x 4).
