Youll see that the first term is 4, and then it keeps on advancing by 5. Infact, notice that the 2nd term is 4+1x5, the 3rd is 4+2x5 and so on... looking at the pattern we can can write: t(n) = 4+ (n-1)5

OpenStudy (anonymous):

can you simplify that to -1+5n?

OpenStudy (anonymous):

yeah..open that bracket 4+ 5n -5 = 5n -1
