Answer:
The second term in the sequence is -9
Step-by-step explanation:
Given the nth term of a sequence to be a(n) = a(n-1)+4 where n is the number of terms of the sequence
If a(1) = -13... (1)
The second term of the sequence is generated for n= 2:
a(2) = a(2-1)+4
a(2) = a(1)+4... (2)
Substituting equation 1 into 2
a(2) = -13+4
a(2) = -9
The second term in the sequence is -8
Answer:
Step-by-step explanation:
- We started at 1
- And it seems that index after index it multiplies by 3
- The formula for the geometric sequence defined implicitly is a(n) =a(1)r^(n-1)
