Question

What is the value of the 11th term in the sequence -3, -6, -12, -24, ...?

Answer 1

Answer:

1536 is the 11th term of the sequence

Answer 2

Answer:

- 3072

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 = - 3 and r = - 6 ÷ - 3 = 2, thus

$a_{11}$ = - 3 × $2^{10}$ = - 3 × 1024 = - 3072
