the sequence is Un=2n2
It is: 9n+5 and so the next term is 50
5+9n
The nth term is 2n2. (One way to find that is to notice at all the numbers are even, then divide them by 2. The sequence becomes 1, 4, 9, 16, 25, which are the square numbers in order.)
Nth term With the nth term you substitute the n for the term number (e.g. 50) so the 50th term in 2n+3 would be 2x50+3=103
The nth term is 2n2. (One way to find that is to notice at all the numbers are even, then divide them by 2. The sequence becomes 1, 4, 9, 16, 25, which are the square numbers in order.)

50 - 32 = 18 18/50 = 36/100 Answer: 36%
-n2+2n+49
32 + 25x + 18 = 50 + 25x
50
