Answer:
D
Step-by-step explanation:
The solution is B. In each equation, it uses parenthesis to group operations. On the left, each pair repeats one number either 1.6 and 4.2. On the right is written the reduced form by writing the expression with a greatest common factor.
Option A is incorrect since 1.6 is not the GCF which appears in each parenthesis.
Option B is incorrect because the operation in the parenthesis is multiplication and not addition.
Option C is incorrect because 1.6 as a GCF is applied using multiplication.
Option D is correct since 1.6 does occur as a GCF in each parenthesis. It also has written correctly (4.2 +7) since addition is the operation between the parenthesis.

Answer:
Step-by-step explanation:
> 2f%283-1%29+%2B+3%2A3-> 2f%282%29+%2B+9-> 2%282%29+%2B9->4%2B9=13
a%5B3%5D=+13...third term
n=4
-> 2f%284-1%29+%2B+3%2A4-> 2f%283%29+%2B+12-> 2%2813%29+%2B12->26%2B12=38
a%5B4%5D=+38.....forth term
