Question

Fa(1) = -13

a(n) = a(n-1)+4

Find the 2nd term in the sequence.

Answer 1

The 2nd term in the sequence is -9.

Explanation:

fa(1) = -13

a(n) = a(n-1)+4

Find the 2nd term in the sequence.

The sequence is an Arithmetic sequence.

Here the 1st term = -13

An = A(n-1) + 4

Therefore, the common difference (d) = 4

2nd term = first term + common difference

2nd term = -13 + 4 = -9

The answer is -9.

THEREFORE, The 2nd term in the sequence is -9.

Answer 2

The 2nd term in the sequence is -9.

Explanation:

We have that:

`a(1) = -13`

`a(n) = a(n-1) + 4`

Find the 2nd term in the sequence.

This is a(2). So

`a(2) = a(2-1) + 4`

`a(2) = a(1) + 4`

Since a(1) = -13.

`a(2) = -13 + 4 = -9`

The 2nd term in the sequence is -9.
