Detailed Explanation & Answer
Let the two consecutive numbers be n and n + 1.

The difference between their squares is given by the equation:
(n + 1)^2 - n^2 = 35.
n^2 + 2n + 1 - n^2 = 35.
2n + 1 = 35.
2n = 35 - 1,
n = 17.

Thus, the smaller number is 17.
माना कि दो क्रमागत संख्याएँ n और n + 1 हैं।

उनके वर्गों के बीच का अंतर समीकरण द्वारा दिया गया है:
(एन + 1)^2 - एन^2 = 35.
n^2 + 2n + 1 - n^2 = 35.
2एन + 1 = 35.
2एन = 35 - 1,
एन = 17.

अत: छोटी संख्या 17 है।
