Answer 1

Answer:

Step-by-step explanation:

Let there be a value of x such that sum of the numbers of the houses preceding the house numbered x is equal to the sum of numbers of the houses following it.

(1+2+3+........+[x-1]) = [(x+1)(x+2),....,48,49]

(x-1)/2[1+x-1] =(49-x)/2[x+1+49]

(x-1)x=(49-x)(x+50)

x²-x=49x+2450-x²-50x

x²-x =2450-x²-x

x²+x²-x+x=2450

2x²=2450

x²=2450/2

x²=1225

x=√1225

x=35

(1+2+3+.......+34) = (36,37,.......,48,49
