25-3n = 22
tn = 2n2 + 3n - 2
What is the 2nd term of 3n-2?
123456789 * * * * * The nth term is 3n
3n^2 - n + 1
If that's +25, that factors to (3n - 5)(3n - 5) or (3n - 5)2
3n + 2n = 25 5n = 25 n = 5
you have answered your own question 19 - 3n
Just plug in 30 for n in 3n-1. The answer is 89.
[ 13n + 25 ] is.
3n(n+1] + 5 is the nth term
The nth term is 2 + 3n.
