What are the first four terms of the sequence given by the formula below?

an= -2n + 4

Verified Answer :

In order to solve this problem, We need to substitute the first four numbers (1,2,3,4) for n. After this we calculate:
First item:
a1= -21 + 4=-2+4=2
Second item:
a2= -2
2 + 4
=-4+4=0
Third item:
a3= -23 + 4
=-6+4=-2
Forth item:
a4= -2
4 + 4
=-8+4=-4

So the first 4 items are: 2,0,-2,-4..
