It is geometric because it is increasing by a common factor. If you multiply the previous number by 6 you receive the next number. If it were arithmetic you would add the number, not multiply.
        
             
        
        
        
Hello from MrBillDoesMath!
Answer:
n = 5
Discussion:
Let the original number be "n"  Translating the problem  statement to mathematical symbolism:
n + 4 = 19 - 2n                   =>  add 2n to both sides
n + 2n + 4 = 19 - 2n + 2n  =>  combine like terms
3n + 4 = 19                        => subtract 4 from both sides
3n = 19 -4  = 15                 => divide both sides by 3
n = 15/3 =5
Check: Does 5 +4 = 19 - 2(5)? Does 9 = 9? Yes. so the value for n is confirmed correct.
Thank you,
MrB
