Answer 1

4,782,969

Multiply by 3 until you get to the 14th term

Answer 2

4782969

Explanation:

A geometric sequence is given as;

aₓ= ar⁽ˣ⁻¹⁾

Where a= first term and r = common ratio.

From question,

a=3 and r=3 and x= 14

Substitute into equation;

a₁₄= 3* 3⁽¹⁴⁻¹⁾

a₁₄ = 3* 3¹³

a₁₄ =4782969
