Question

C(1)=−20
c(n)=c(n−1)+10

Find the second term in the sequence.
​

Answer 1

c(2) = -10

Explanation:

The first equation says that the first term of the sequence is -20.

The second equation is saying that to find any term of the sequence, add 10 to the previous term.

c(2) = c(2-1) + 10

c(2) = c(1) + 10

c(2) = -20 + 10 = -10
