Answer:2,7,12,19
Step-by-step explanation:
a2=a2-1+5=-3+5=2
a3=a3-1+5=a2+5=2+5=7
a4=a3+5=12 and continue so on

Initial value: x = 0
![f(0) = 7(3\sqrt[3]{2})^0](https://tex.z-dn.net/?f=%20f%280%29%20%3D%207%283%5Csqrt%5B3%5D%7B2%7D%29%5E0%20)


The initial value is 7.
The domain is all real numbers.
The range is all real numbers greater than zero.
Answer:
52 cards
Step-by-step explanation:
call the amount he started with " x "
then he bought 8 cards
so the new equation is
x+8
then he lost half of his cards
so now the equation is
(x + 8 )/2
that amount to 30 cards as per what is given in the problem
so now the equation is
( x + 8 )/2 = 30
solve using inverse operations and simplifying
( x + 8 )/2 = 30
*2 *2
x + 8 = 60
-8 -8
x = 52
