Question

Find the first four terms of the infinite sequence defined explicitly by the following rule.

f(n)= 4n - 2

Answer 1

The only thing that you should do is to put 1, 2, 3, and 4 instead of the n and then you will get the first four terms! 

f(1) = 4(1) - 2 = 2 
f(2) = 4(2) - 2 = 6
f(3) = 4(3) - 2 = 10 
f(4) = 4(4) - 2 =  14 

Have a great day!
