The numbers : \frac{- 1 + 573}{2}, \frac{- 1 + 573}{2} + 1 or \frac{- 1 - 573}{2}, \frac{- 1 - 573}{2} + 1

解答ステップ

Represent the numbers with

x

First number : x

Consecutive number : x + 1

A.T.Q.:

x (x + 1) = 143

解く

x (x + 1) = 143 : x = \frac{- 1 + 573}{2}, x = \frac{- 1 - 573}{2}

挿入

x = \frac{- 1 + 573}{2} : \frac{- 1 + 573}{2} + 1

挿入

x = \frac{- 1 - 573}{2} : \frac{- 1 - 573}{2} + 1

The numbers : \frac{- 1 + 573}{2}, \frac{- 1 + 573}{2} + 1 or \frac{- 1 - 573}{2}, \frac{- 1 - 573}{2} + 1
