Answers
Solution 1 :-
Let the three consecutive number be x , ( x + 1) and ( x + 2 )
According to the question ,
The sum of three consecutive numbers is 150
Therefore ,
x + ( x + 1 ) + ( x + 2) = 150
x + x + 1 + x + 2 = 150
3x + 3 = 150
3x = 150 - 3
3x = 147
x = 147/3
x = 49
Three consecutive numbers are :-
x = 49
x + 1 = 49 + 1 = 50
x + 2 = 49 + 2 = 51
Solution 2 :-
Let the three consecutive even numbers be (x +2) ( x + 4) , ( x + 6)
According to the question ,
The sum of three consecutive even numbers are 144 .
( x + 2 ) + ( x + 4) + (x + 6) = 144
x + 2 + x + 4 + x + 6 = 144
3x + 12 = 144
3x = 144 - 12
3x = 132
x = 132/3
x = 44
Therefore , three consecutive numbers are:-
x + 2 = 44 + 2 = 46
x + 4 = 44 + 4 = 48
x + 6 = 44 + 6 = 50
Solution 3 :-
Let three consecutive odd numbers be( x +1), ( x+3) , ( x + 5 )
According to that question ,
The sum of three odd numbers are 177
Therefore ,
(x + 1) ( x + 3) +( x + 5) = 177
x + 1 + x + 3 + x + 5= 177
3x + 9 = 177
3x = 177 - 9
3x = 168
x = 168/3
x = 56
Therefore , The three consecutive odd numbers are :-
x + 1 = 56 + 1 = 57
x + 3 = 57 + 3 = 60
x + 5 = 57 + 5 = 62
