Question 396387
The last of three consecutive numbers increased by ten is equal to the sum of the first two consecutive numbers.
Here is what i have so far:
Let 1st number = x
2nd number = x+1
3rd number = x+2
It says,"The last of three consecutive numbers increased by ten ", that would be:
(x+2) + 10 = x+12
"is equal to the sum of the first two consecutive numbers."
x + 12 = x + (x+1)
x + 12 = 2x + 1
12 - 1 = 2x - x
11 = x
:
11, 12, 13 are the numbers
Check it in the statement:
"The last of three consecutive numbers increased by ten is equal to the sum of the first two consecutive numbers."
13 + 10 = 11 + 12
