Ekadhikena Purvena

Meaning : "By one more than the previous one"

This sutra is used exclusively for numbers ending with 5.

For numbers ending with 5 the LHS will be 25.

The RHS will be the product of the other digits with its ekadhikena.

Examples :

25² = (2 * 3) | 25 = 625

35² = (3 * 4) | 25 = 1225

45² = (4 * 5) | 25 = 2025

55² = (5 * 6 ) | 25 = 3035

65² = (6 * 7) | 25 = 4225

75² = (7 * 8) | 25 = 5625

105² = (10 * 11) | 25 = 11025

125² = (12 * 13) | 25 = 15625

175² = (17 * 18) | 25 = 30625
