The sum of two consecutive integers is 169, how do you find the two integers?

Answer 1

Let #n = # the smaller of the two integers, then #n+1# is the greater of the two integers. The sum of the two integers is:

#n + (n+1) = 169#

Combine like terms:

#2n + 1 = 169#

Subtract 1 from both sides:

#2n = 168#

Divide both sides by 2:

#n = 84#

Then

#n+1 = 85#

check:

#84 + 85 = 169#

#169 = 169 larr # this checks

Let ( x ) be the first integer and ( x + 1 ) be the consecutive integer. The sum of the two integers is ( x + (x + 1) = 2x + 1 ). Given that the sum is 169, we have the equation ( 2x + 1 = 169 ). Solving for ( x ), we get ( x = 84 ). Therefore, the two consecutive integers are 84 and 85.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
