Choose the equation that could be used to find two consecutive integers whose sum is 67.
n + (n + 2) = 67
n − (n + 1) = 67
n + n = 67
n + (n + 1) = 67

consecutive integers are whole numbers like 1, 2, 3, 4, ...
basically numbers that follow one after the other
jimthompson5910 (jim_thompson5910):
so let's say 'n' is the first (smaller) integer
jimthompson5910 (jim_thompson5910):
what is the next consecutive integer
OpenStudy (anonymous):
2
jimthompson5910 (jim_thompson5910):
no

n is the first integer
____ is the next consecutive integer
OpenStudy (anonymous):
O
jimthompson5910 (jim_thompson5910):
still no
jimthompson5910 (jim_thompson5910):
say n = 3
the next integer would be 4
jimthompson5910 (jim_thompson5910):
4 = 3+1

so replace 3 with what it is equal to
OpenStudy (anonymous):
so 4
jimthompson5910 (jim_thompson5910):
3 = ???
jimthompson5910 (jim_thompson5910):
look above to what i set 3 equal to
OpenStudy (anonymous):
3?

jimthompson5910 (jim_thompson5910):
i said n = 3 above, see it
jimthompson5910 (jim_thompson5910):
so n = 3
4 is the next consecutive integer
so
4 = 3+1
4 = n + 1 ... replace 3 with n (since n = 3)
jimthompson5910 (jim_thompson5910):
if n is the first, then n+1 is the next consecutive integer
OpenStudy (anonymous):
um im so confused
jimthompson5910 (jim_thompson5910):
where are you stuck

the whole thing
jimthompson5910 (jim_thompson5910):
do you have your notes with you? or your book with you?
OpenStudy (anonymous):
no
jimthompson5910 (jim_thompson5910):
ok I recommend getting them out and going over them again
jimthompson5910 (jim_thompson5910):
look for the term "consecutive integer" and problems dealing with them

there's probably an example showing how to solve problems like that
