The recursive formula for this sequence is = -7;
=
+ 10
Step-by-step explanation:
The recursive formula of the arithmetic sequence is:
= first term;
=
+ d
is the first term in the sequence
is the nth term in the sequence
the term before the nth term
- n is the term number
- d is the common difference
∵ The sequence is -7 , 3 , 13 , 23 , 33 , 43 , ........
∵ 3 - (-7) = 3 + 7 = 10
∵ 13 - 3 = 10
∵ 23 - 13 = 10
- There is a constant difference 10 between the consecutive terms
∴ The sequence is an arithmetic sequence
∵ The first term is -7
∴ = 7
∵ The common difference is 10
∴ d = 10
- Substitute in the formula above by -7 and d by 10
∴ = -7;
=
+ 10
To check the formula find the second term
∵ n = 2
∴ = -7;
=
+ 10
∴ =
+ 10
∵ = -7
∴ = -7 + 10 = 3 which is right
The recursive formula for this sequence is = -7;
=
+ 10
