The formula for the arithmetic sequence will be:
Step-by-step explanation:
Given
- a₁ = -1
- d = -7
- We know that we can get the next term of the Arithmetic sequence by taking the current term and adding the common difference.
so
a₂ = a₁ + d
= -1 + (-7) ∵ a₁ = -1
= -1 - 7
= -8
similarly,
a₃ = a₂ + d
= -8 + (-7)
= -8 - 7
= -15
and so on
Thus, the Arithmetic sequence becomes
a₁, a₂, a₃, ...
-1, -8, -15, ...
as
- a₁ = -1
- d = -7
Therefore, An arithmetic sequence has a constant difference d and is defined by
substituting a₁ = -1 and d = -7
Hence, the formula for the arithmetic sequence will be:
