Question

The sum of three consecutive numbers is 372. What is the 1st number?

Answer 1

Answer:

The 1st number is 123.

Step-by-step explanation:

Let the numbers are x,x+1,x+2.

ATQ: x+x+1+x+2=372

3x+3=372

3x=372-3=369

x=369/3=123

Answer 2

$\sf{Answer}$

Step-by-step-explanation:-

Given :-

• Sum of 3 consecutive numbers is 372

To find :-

1st number

Explanation:-

What is consecutive numbers?

The consecutive numbers are that mumbers difference should be 1 & should take in a sequence

Eg :- 1, 2, 3 are consecutive numbers

Solution:-

So,

Let ,

Consecutive numbers be ,

• x
• x + 1
• x + 2

And given,

These sum is equal to 372

x + (x + 1) + (x +2 )= 372

x + x + 1 + x +2 = 372

x + x + x + 1 +2 = 372

3x + 3 = 372

3x = 372 - 3

3x = 369

x = 123

x + 1 = 123 + 1

x + 1 = 124

x + 2 = 123 +2

x + 2 = 125

So, first number is 123

Verification :-

We got three numbers Its should be 372 & Those numbers should be consecutive numbers

123 + 124 + 125= 372 (satisfied)

123 , 124, 125

Consecutive numbers and difference is 1

So,

First number is 123
