✎ Answer

The tenth term is .

✎ Solution:

Given that:

• the first term a₁ =
• the number of terms n = 10
• the common ratio r =

✍︎ Note that the common ratio can be found by dividing any term except the first term, by its preceding term.

• Thus, = = =

Using the formula for finding the nth term im a geometric sequence:

aₙ=a₁r⁽ⁿ⁻¹⁾

Plugging in the values and solving for the tenth term a₁₀.

• a₁₀ =

• a₁₀ = (

• a₁₀ =

• ∴ a₁₀ =
