The correct answer is:  [C]:  " 5 " .
__________________________________________________________
                                →  " a = 5 " .

Explanation:
__________________________________________________________ 
Given:  " a + 1 <span>− 2 = 4 " ; Solve for "a" ; 
4 + 2 = 6 ; 
6 </span>− 1 = 5 ;   →  a = 5 ;
To check our work:
5 + 1 − 2 = ? 4 ?? ;  
5 + 1 = 6 ; 
6 − 2 = 4.  Yes!
So the answer is:  [C]:  " 5 ".

Answer: 
The initial amount a = 1
 The growth or decay factor  = 0.01025
Step-by-step explanation:
The exponential function.
 y = 0.01025^x
The initial amount a = 1
 The growth or decay factor  = 0.01025
The exponential equation can be rewritten as Y = 1(0.01025)^x
