Here's the solution,

the opposite angles of parallelogram are equal, so, Angle G = Angle E

=》3x + 11 = 5x - 9

=》5x - 3x = 11 + 9

=》2x = 20

=》x = 10

value of x = 10

now, Angle G = 5x - 9

=》(5 × 10) - 9

=》50 - 9

=》41°

Angle G and Angle F are supplementary, so

=》 41° + Angle F = 180°

=》Angle F = 180° - 41°

=》Angle F = 139°

 The correct option is

(B) f(n+1)=f(n)-5.

Step-by-step explanation:  We are given to select the correct recursive formula that can be used to generate the following sequence :

f(1)=6,n\geq1,\\\\6,1,-4,-9,-14,...

Let f(n) denote the nth term of the given sequence. Then, we note that

f(1)=6,\\\\f(2)=1=6-5=f(1)-5,\\\\f(3)=-4=1-5=f(2)-5,\\\\f(4)=-9=-4-5=f(3)-5,\\\\f(5)=-14=-9-5=f(4)-5,\cdots

Therefore, the recursive formula can be written as :

f(n+1)=f(n)-5.

Thus, the required recursive formula is f(n+1)=f(n)-5.

Option (B) is CORRECT.
