Question

Can someone help me please

Answer 1

Suppose the numbers are n, (n+1) and (n+2) where n is an integer
Then, , therefore

so it is not possible as n an integer
You can also see this by considering the sequences:
55, 56, 57 whose sum is 168
56, 57, 58 whose sum is 171
so there are no three consecutive numbers with sum 170.

Answer 2

Use the formula x+x+1+x+2 or 3x+3=170 to find x. x is the first number. Then add x+1 to find the second number. Then add x+2 to find the third final number.
x will equal 167/3 which is a decimal, so just plug it in to the 3 equations I mentioned above to find your 3 consecutive numbers. More questions? Just ask me!
