Give the 3rd and 7th terms using the sequence formula tn = (n – 3)2

Question

anonymous · Answer

I haven't done much for sequences, but I think I can solve this if I understand the notation:

Does this read as,   t of n = (n-3) squared?

anonymous · Answer

yes

jim_thompson5910 · Answer

Assuming that the sequence starts at n=1, the third term is 

$$t_{3} = (3-3)^2=0^2=0$$

and the 7th term is 

$$t_{7} = (7-3)^2=4^2=16$$

anonymous · Answer

Aren't we also supposed to plug in the value of the previous function?  Or am I mixing it up with summation?

You're thinking of a recursive sequence uberl337h4xx0r, and summation generally refers to a series.
