Question

For the sequence an = 6. (1/3)n, a4 is _________

Answer 1

Answer:

The a₄ term is 8

Step-by-step explanation:

aₙ = 6.(1/3)n

To find a₄ put n = 4

a₄ = 6(1/3).4

 = 2.(4)

 = 8

Answer 2

Here, a₄ term is 8.

Explanation:

aₙ = 6. (1/3) n -> (1)

a₄ that is n = 4 -> (2)

the formula is:

aₙ = a + (n-1) d

Substitute equation (2) in (1)

we get,

a₄ = 6(1/3).4

     = 2. (4)

      = 8

Therefore, a₄ term is 8.
