Hi,
Answer: 3
Step-by-step explanation:
Given data:
The first term of the G.P. = a = 2/3
t6 = 162
To find: value of r
We know that the formula for nth term of G.P. is,
tn = a * rⁿ⁻¹
where,
a = first term
r = common ratio
Here we are given, n = 6
∴ t6 = (2/3) * r⁶⁻¹
⇒ 162 = 2/3 * r⁵
⇒ r⁵ = (162 * 3) / 2
⇒ r = 243^(1/5)
⇒ r = 3
Thus, the value of r is 3.
Hope it is helpful!!!
