Explanation:
#"integers are 1 unit apart"#
#"let n be an integer then a consecutive integer is n + 1"#
#rArrn+(n+1)=211larr" solve for n"#
#rArr2n+1=211#
#"subtract 1 from both sides"#
#2ncancel(+1)cancel(-1)=211-1#
#rArr2n=210#
#"divide both sides by 2"#
#(cancel(2) n)/cancel(2)=210/2#
#rArrn=105" and " n+1=105+1=106#
#"thus the 2 consecutive integers are " 105" and "106#
