Find the 8th term in the sequence with this explicit formula: c(n) = -6 + 5(n - 1)

We are given this explicit formula :

In order to find eighth term let us plug n as 8 in this formula:

subtracting 8-1 first using pemdas rule

multiplying 5 and 7

subtracting 35-6

c(8) = 29

So eighth term is 29.
