Question

What is the value of a1 in the sequence?

−4, −2, −12, −14, ...




​ −14

−4

​ −2 ​

​ −12 ​

Answer 1

`a_1,\ a_2,\ a_3,\ a_4,\ ...-\text{the sequence}\\\\\text{We have}\\\\-4,\ -2,\ -12,\ -14,\ ...\\\\\boxed{a_1=-4}`

Answer 2

Option B.

Explanation:

The given sequence is

-4, -2, -12, -14, ...

We need to find the value of a₁.

We know that
`a_n` represents the nth term of a sequence. So, a₁ represents the first term of the sequence.

From the given sequence it is clear that the first term of the sequence is -4. So, we conclude that

`a_1=-4`

The value of a₁ in the sequence is -4.

Therefore, the correct option is B.
