Question

Give the 5th and 10th term for the sequence formula below.
tn = 1 + 6n

Answer 1

We might need a place to start. \(t_{1}\) maybe?

Answer 2

Perhaps assume that
t(1) = 1 + 6(1) = 7 and then

t(2) = 1 + 6(2) = 13
t(3) = 1 + 6(3) = 19
t(4) = 1 + 6(4) = 25
t(5) = 1 + 6(5) = 31

This does not look like a typical sequence notation:
e.g. t(n+1) = t(n) + 5 with t(1) given, but perhaps the question as written is correct.
