Question

Please someone help i dont understand

ill upload the rest in a second

Answer 1

Question 5:
T1=-11+6(1-1)=-11
T2=-11+6(2-1)=-5
T3=-11+6(3-1)=1
.
.
.
Tn=-11+6(n-1)//
Option one is correct

Question 6:
A7=-9-4(7-1)
=-33//

Question 7:
Tn=0.5*4^n-1
Therefore T6=0.5*4^6-1=512//
Moreover 0.4/2=1/4, 2/8=1/4…
Therefore option two is correct

Question 4:
A2=A(2-1)+5=A1+5=-24+5=-19
.
.
.
A4=A(4-1)+5=-9//
