Question

the sum of two consecutive natural number is 313. find the number

Answer 1

Let 1 number be `x` .  Since the numbers are consecutive, the other number would be `x + 1.`

so, x + (x + 1) = 313
x + x + 1 = 313
2x + 1 = 313
2x = 313 - 1
2x = 312
x = 312/2
x = 156

so,
x = 156
nd x + 1 = 157
so, the two numbers are 156 and 157...

now, you can also add them ..
