Answer:
b1 = 2 ; r = 3
Step-by-step explanation:
Given that :
if b3 −b1 = 16 and b5 −b3 = 144.
For a geometric series :
Ist term = a
Second term = ar
3rd term = ar^2
4th term = ar^3
5th term = ar^4 ;...
If b3 - b1 = 16;
ar^2 - a = 16
a(r^2 - 1) = 16 - - - (1)
b5 - b3 = 144
ar^4 - ar^2 = 144
ar^2(r^2 - 1) = 144 - - - - (2)
Divide (1) by (2)
a(r^2 - 1) / ar^2(r^2 - 1) = 16 /144
a / ar^2 = 1 / 9
ar^2 = 9a
Substitute for a in ar^2 - a = 16
9a - a = 16
8a = 16
a = 2
From ar^2 - a = 16
2r^2 - 2 = 16
2r^2 = 16 + 2
2r^2 = 18
r^2 = 18 / 2
r^2 = 9
r = √9
r = 3
Hence ;
a = b1 = 2 ; r = 3
Answer:
Step-by-step explanation: -3
Answer:
(7,-2)
Step-by-step explanation:
G is currently at (2, 0)
(2+5, 0-2) becomes (7, -2)
solution: option D is correct i.e., withdrawing money from savings.
explanation:
if someone is taking home loan then he has to pay it back also. but if he is withdrawing money from savings then he will don't have money to return in future. so he should save as much as he can.
so withdrawing money from savings would have a negative impact on determining eligibility for a home loan.
