OPEN CHALLENGE​

Answer 1

4x5x6x7=840,

so 4, 5, 6, 7 are the answers

Answer 2

Answer:

4,5,6,7

Step-by-step explanation:

Let the four consecutive numbers be:

Let the four consecutive numbers be:x, x+1, x+2, x+3

Let the four consecutive numbers be:x, x+1, x+2, x+3(consecutive numbers: numbers which occur one after the other)

now, as given, the sum of all the numbers is 840

so, x(x+1) (x+2) (x+3). = 840 (x^2 + x) (x^2+3x+2x+6)= 840

x^4+6x^3+11x^2+6 = 840

= 840by solving this quadratic equation, we get n= 4

so, since we assumed the conducive numbers as:

x=4

x+1= 4+1=5

x+2= 4+2=6

x+3= 4+3=7

Hence, the four consecutive numbers are: 4,5,6,7
