2. Consecutive Integers Consecutive Integers: Use: x, x + 1, x + 2, …+1 +1
Consecutive Integers:
Use: x, x + 1, x + 2, …
x x+1 x+2 +2 +2
Consecutive Odd Integers:
Use: x, x + 2, x + 4, …
x x x+4
SAME! +2 +2
Consecutive Even Integers: 6
Use: x, x + 2, x + 4, …
x x x+4

3. Consecutive Integers
1) Find two consecutive integers whose sum is 225.
a) x = 1st integer
x + 1 = 2nd integer
1st nd = 225
b) x + x + 1 = 225
2x + 1 = 225
2x = 224
x = 112
x + 1 = 113
112 & 113

4. TOO #2 Answer: A) x = 1st even integer x+2= 2nd even integer
B) x + x + 2 = 126
C) 62 & 64

5. Consecutive Integers
3) Find three consecutive odd integers whose sum is 117.
a) x = 1st odd integer
x + 2 = 2nd odd integer
x + 4 = 3rd odd integer
b) x + x x + 4 = 117
37,39,41
3x + 6 = 117
3x = 111
x = 37
x + 2 = 39
x + 4 = 41

6. Consecutive Integers
4) Find 2 consecutive integers such that twice the lesser integer increased by the greater is 49.
a) x = 1st integer
x + 1 = 2nd integer
Write an equation
smallest
largest
b) 2x + x + 1 = 49
16 & 17
3x + 1 = 49
3x = 48
x = 16
x + 1 = 17
