Three times the first of three consecutive odd integers is 3 more than twice the third. The third integer is:
Answer: Option

Let the three integers be x, x + 2 and x + 4.

Then, 3x = 2(x + 4) + 3      x = 11.

Third integer = x + 4 = 15.

Three odd consecutive number.
3, 5, 7 = 3 + 5 + 7 then ans 15.

Let three consecutive odd integers are: x, x+2,x+4.

Three times the first of three integers, so--> 3x; is 3 more than twice the third so--> 3+ 2(x+4).

Then, we get an equation like 3x=3+2(x+4).

So, the third integer is x+4=15.

Odd numbers are never be in form of x, x+2 etc.
Odd no Is in the form of 2x+1.

X+1, X+3, X+5.
3(X+1) = 3+2(X+5),
X = 10.

The Consecutive odd integers are (2x+1, 2x+3, 2x+5). Sub any no.for 'x', you'll get an odd integer.

Now, try solving the question with these three, you'll get X = 5;
That means the 3rd integer, 2X + 5 = 15.

Suppose we take x,x+2,x+4 for odd consecutive numbers;

Then, according to the question, the first among the consecutive number is 3 more than twice the third number.

It means 3x+3=2(x+4) then;
we will get 3x+3=2x+8(now collecting like terms);
then 3x-2x=8-3.

So the third number is x+4----->>>> 9.

Consecutive mean 1 after one. i.e 1, 3, 5, 7etc.
