 An integer is a number without a deci mal or fraction like -5, 0, 32  Consecutive means next  consecutive integers are numbers that co me one after another like -3,-2,-1,0,1,2  they are one apart from the previous or ne xt consecutive integer  If x is one integer, what is the next co nsecutive integer???  and the next one? Consecutive Integers 연속된 정수들 page 174 x+1 x+2

 even consecutive integers -4,-2,0,2,4,6  odd consecutive integers -3,-1,1,3,5,7,9  what is the difference between each pair?  For even consecutive integers, we define th e variable  Let x = even integer, what would be the next even integer?  let x+2 = 1 st consecutive even integer  let x+4 = 2 nd consecutive even integer What about even or odd consecutive integers

 we can define  Let 2x = even integer  let 2x+2 = 1 st consecutive even integer  let 2x+4 = 2 nd consecutive even integer Or

If we define x as an odd integer Let x = odd integer what would the next odd integer be? let x+2 = 1 st consecutive odd integer, jus t like even integers, odd integers are 2 ap art let x+4 = 2 nd consecutive odd integer For odd integers

 we can define it this way  Let 2x + 1 = odd integer  let 2x+3 = 1 st consecutive odd integer  let 2x + 5 = 2 nd consecutive odd integer  There are many ways to define them, as l ong as they are two apart, x-2, x, x+2 are 3 consecutive even or odd integers. Or

1a Let x=even integer Let x+2 = 1 st consecutive even integer 1b x + (x+2) = 118 1c 2x + 2 = 118 2x= 116 x=58 If x=58, then x+2 = 60. The two consecutive ev en integers are 58 and 60. Page 175
