Put n = 1, 2, 3, 4 etc in the expression 5n + 2 and evaluate to get the sequence.
8
Put N = 10 and what you get is U10 = 5*10 + 3 = 50 + 3 = 53.
(2n+3)(n+1)=2n2+5n+3.
it is 8.
Substitute the values 1, 2, 3, etc for n in 35 - 5n
N=3.
5m-5n+5m+5n When simplified: 10m
2
5n + 3 = 14 - 6n <=> 5n +6n = 14 - 3 <=> 11n = 11 => n = 11/11 = 1
-2n
5N + 3 Just add the Ns and put +3 on the end!
