【 】The sum of 4 consecutive integers is 180. What is the fourth numbers in this sequence?
The sum of 4 consecutive integers is 180. What is the fourth number in this sequence?
Solution:
We need to find out the fourth 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 180.
So, we are getting the following equation
x +( x+1)+(x+2) +(x+3) = 180
Or, 4x + 6 = 180
Or, 4x + 6 – 6 = 180 -6[ Deduct 6 from both sides ]
Or, 4x + 0 = 176
Or, 4x = 176
Or, 4x/4 = 176/4
[Divide both sides by 4]
Or, x = 44
Now put the value of x here:
x, x+1,x+2 ,x+3
= 44, 44+1 , 44+2 ,44+3
=44 , 45, 46, 47
So, the fourth number of this sequence is 47.
Answer: 47
