Answer:

3, 6, 12, 24

Step-by-step explanation:

This is a recursive formula which allows the next term in a sequence to be found from the previous term in the sequence

Given

[tex]a_{n}[/tex] = 2[tex]a_{n-1}[/tex] with a₁ = 3, then

a₂ = 2 × a₁ = 2 × 3 = 6

a₃ = 2 × a₂ = 2 × 6 = 12

a₄ = 2 × a₃ = 2 × 12 = 24

Thus the first 4 terms are 3, 6, 12, 24

Answer:

B.[tex]3,6,12,24[/tex]

Step-by-step explanation:

We are given that

[tex]a_n=2a_{n-1}[/tex]

[tex]a_1=3[/tex]

We have to find the first four terms of G.P

Substitute n=2

[tex]a_2=2a_1=2(3)=6[/tex]

Substitute n=3

[tex]a_3=2a_2=2(6)=12[/tex]

Substitute n=4

[tex]a_4=2a_3=2(12)=24[/tex]

Hence, the first four terms of G.P are  given by

[tex]3,6,12,24[/tex]

Option B is true.
