Answer 1

Answer:

a₆ = 972

Step-by-step explanation:

Is it correct?

a₄ = 3a₃ = 3 × 36 = 108

a₅ = 3a₄ = 3 × 108 = 324

a₆ = 3a₅ = 3 × 324 = 972

Answer 2

Answer:

Step-by-step explanation:

Remark

You could do this two ways: one with a formula and one without. I'll do it both ways.

With Formula

a_n = 4 * 3^(n - 1)

a_6 = 4 * 3^(5)

a_6 = 4 * 243

a_6 = 972

Without

a1 = 4

a2 = 4 * 3^(2 - 1)

a2 = 4 * 3

a2 = 12

a3 = 3* a_n-1

a3 = 3 * 12

a3 = 36

a4 = 3*a_3

a4 = 3*36

a4 = 108

a5 = 3 * a_(n - 4)

a5 = 3 * 108

a5 = 324

a6 = 3 * 324

a6 = 972 which is the same answer you got by using a formula
