consecutive numbers

Question

sum of the first ,second, and fourth consecutive integers,simplified:

Answer 1

Integers are all whole numbers,

both positive and negative, and zero.

 

..., -3, -2, -1, 0, 1, 2, 3, ...

 

There is no such thing as "the first

integer"

 

If you mean "write an expression

for the sum of  3 integers given 

the 2nd integer is next consecutive

after the first and the 3rd integer is

the 4th consecutive integer" 

 

Let x = 1st integer 

x+1 = 2nd integer

x+3 = 3rd integer

 

Sum:  x + x+1 + x+3 = 3x + 4
