term in the sequence

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
