Question

Which of the following is a Recursive Formula for an Arithmetic Sequence?

an = 6n – 9

an = -3 + 6(n – 1)

a1 = -3, an = an-1 + 6

a1 = -3, an = 6an-1
Pls I require assistance.

Answer 1

The Recursive formula for an Arithmetic Sequence is a1 = -3, an = an-1 + 6.

What is Arithmetic sequence ?

An arithmetic sequence is a sequence where each term increases by adding/subtracting some constant k.

Given:

an = -3 + 6(n – 1)

a1= -3

a2= 3

a3 = 9

Here the common difference is 6 and first term is -3

Hence, the recursive formula is a1 = -3, an = an-1 + 6.
