Question

The explicit rule for the series 0, 1, 2, 3, ... is

given by an = n - 1. Shyla's attempt to find the fifth

term in the sequence is shown below:

a5 = 5-1 = 4

Looking at the sequence, the 4th number

would be 3.

Identify Shyla's mistake and find the correct

answer.

Answer 1

this

Explanation:

Which did you include in your response?

The correct answer is 4.

After using the rule for n = 5, she was done.

She tried to look for the fourth term after she arrived at 4; however, the problem asked for the fifth term.

Answer 2

Shyla's have not done any mistake.

Explanation:

We have given that, The explicit rule for the series 0, 1, 2, 3, ... is given by
`a_n = n - 1`.

Shyla's attempt to find the fifth term in the sequence is shown below:

i.e. substitute n=5

`a_5 = 5 - 1=4`

Looking at the sequence, the 4th number would be 3.

According to explicit rule the fourth term is

`a_4 =4-1=3`

Which is correct.

Similarly all the terms will get in this way.

So, Shyla's have not done any mistake.
