Answer:
The third number in the sequence 31, 32, 33, 34 is 33
Explanation:
let first number be the smallest number be x.
Consecutive numbers are those numbers that follow each other in order and they should have a difference of 1 between every two numbers.
Then, the four consecutive integers are x , (x+1), (x+2) , (x+3)
Given: the sum of 4 consecutive integers is 130.
From the given condition we have,

Like terms states that contain the same variables raised to the same power.
Combine like terms we get,

Subtract 6 from both the sides, we get

Simplify we get,

Divide both sides by 4;
On simplify we get, the value of x i.e,

the sequence we have, 31, 32, 33, 34,
therefore, the third number in the sequence is, 33.
