The sum of 4 consecutive integers is 354. What is the second number in this sequence?

Solution:

We need to find out the  second  number  from  consecutive integer numbers' sequence.

 

                      Step-1:

We have to have knowledge about integer number.An integer number does not have any fractional part.It can be positive or negative number.

Now you have to understand about consecutive integer number.The difference between two consecutive integer numbers  is always 1.

 

                Step-2:

Say,the first integer number is x.

So, the second integer number will be x+ 1. Thus, the third consecutive integer number will be x+2 .Besides,the fourth integer number will be x+3.

Have a look here.

The four consecutive integer numbers are x, x+1,x+2 ,x+3 respectively.

                  Step-3:

According to the conditions,the sum of 4 consecutive integer numbers will be 354.

 

So, we are getting the following equation

 

x +( x+1)+(x+2) +(x+3)  = 354

Or, 4x + 6 = 354

Or, 4x + 6 – 6 = 354 -6[ Deduct 6 from both sides ]

Or, 4x + 0 = 348

Or, 4x = 348

Or, 4x/4 =  348/4

[Divide both sides by 4]

Or, x = 87

Now put the value of x here:

x, x+1,x+2 ,x+3

= 87, 87+1 , 87+2 ,87+3

=87,   88,    89,    90

So, the second number of this sequence is 88.

Answer: 88
