Qt = 16.
Because since rs Is equal to qr since r is the midpoint of qs. So qr is 8 and because s is the midpoint of the whole line. I multiply it by 2. Giving me 16 for the whole line
Let one no. be x.
then another no. = (19-x).
x - (19 - x ) = 55
2 x - 19 = 55
x = 37
another no. = 19 - 37 = -18
Can you follow me and like me please? I hope i can help you more.☺
The answer to the problem is obvious it’s BLANK
The sum of a geometric sequence is:
s(n)=a(1-r^n)/(1-r) in our case:
s(n)=3(1-4^n)/(1-4)
s(n)=-(1-4^n)
s(n)=(4^n)-1 and s=1023
(4^n)-1=1023
4^n=1024
n ln4=ln1024
n=(ln1024)/(ln4)
n=5
