The second and fifth terms of a geometric progression (g.p) are 1 and 8 respectively. Find the common ratio,first term, and the eight term.
ar = 1
ar^4 = 8
Now divide and you get
r^3 = 8
r = 2
so, a = 1/2
T8 = ar^7 = 2^6 = 64
Correct answer
The answer that it gave me i don't understand how it came to that finnal answer
The first term
Answer
is it the full
Thanks
Pls how did u get 64?????
Are you sure this thing is correct? My teacher would not toleorate ohh
If the second and the fifth terms of a geometric progression are 4 and 32 respectively,
find the first term.
