Step-by-step explanation:
the fith term of a G.P is 8 times the 2nd term.
Hence, common ratio is 2.
Answer:
The common ratio is 2
Step-by-step explanation:
T_n = ar^(n-1)
T_5 = 8(T_2)
r = ?
T_5 = ar^4
T_2 = ar
Therefore
ar^4 = 8ar
Divide both sides by ar, we have
r³ = 8
Taking the cube root of both sides, the result is
r = 2
The common ratio is 2
