Question

Find the 13Th term of geometric sequence 1,2,4,

Answer 1

Answer:

a₁₃ = 4096

Step-by-step explanation:

The n th term of a geometric sequence is

$a_{n}$ = a₁ $(r)^{n-1}$

where a₁ is the first term and r the common ratio

Here a₁ = 1 and r = $\frac{a_{2} }{a_{1} }$ = $\frac{2}{1}$ = 2 , then

a₁₃ = 1 × $2^{12}$ = 4096
