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

  3. Consecutive Integers 1) Find two consecutive integers whose sum is 225. a) x= 1st integer x + 1= 2nd integer 1st + 2nd = 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 • 37,39,41 b) x + x + 2 + x + 4 = 117 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 • 16 & 17 b) 2x + x + 1 = 49 3x + 1 = 49 3x = 48 x = 16 x + 1 = 17
