find 3 consecutive integers such that the sum of the twice the first and the third is 748.

To find three consecutive integers, we can assign a variable to represent the first integer. Let's call it "x".

The consecutive integer after x would be x + 1, and the consecutive integer after that would be x + 2. So, the three consecutive integers can be represented as x, x + 1, and x + 2.

According to the given information, the sum of twice the first integer (2x) and the third integer (x + 2) is 748.

So, we can set up the equation as follows:

2x + (x + 2) = 748

Now, let's solve the equation to find the value of x:

3x + 2 = 748

Subtracting 2 from both sides:

3x = 746

Dividing both sides by 3:

x = 746 / 3

x ≈ 248.66

Since x represents an integer, we can round it to the nearest whole number:

x ≈ 249

Now that we have the value of x, we can find the three consecutive integers:

First integer: x = 249
Second integer: x + 1 = 249 + 1 = 250
Third integer: x + 2 = 249 + 2 = 251

Therefore, the three consecutive integers are 249, 250, and 251.
