Question

Find the first 5 terms of the sequence (explicit):
a n = 3n-1

Answer 1

First term:

an = 3n - 1

a1 = 3(1) - 1

a1 = 3 - 1

a1 = 2

So the first term is a1 = 2

-------------------------------------------------------


Second term:

an = 3n - 1

a2 = 3(2) - 1

a2 = 6 - 1

a2 = 5

So the first term is a2 = 5

-------------------------------------------------------

I'll let you finish and find the next 3 terms

Answer 2

oops meant to say "So the second term is a2 = 5"
