Find the first four terms of the sequence represented by the expression 15 + 4n + 1.
19; 79; 1,039; 16,399
31; 79; 271; 1,039
23, 27, 31, 35
none of these
Maybe you mean 15 + 4(n+1)???
that would be 15 + 4 n + 4 = 19 + 4 n
if n = 1 it is 23
if n = 2 it is 27
if n = 3 it is 31
if n = 4 it is 35
If n starts from (0,1,2 or 3)
Assuming stats from 0
15+1=16
Assuming n starts from 1
15+4+1=20
What do you think?
To find the first four terms of the sequence represented by the expression 15 + 4n + 1, you need to substitute the values of n starting from 0 and incrementing by 1 each time.
So, let's plug in the values of n:
For n = 0: 15 + 4(0) + 1 = 15 + 0 + 1 = 16.
For n = 1: 15 + 4(1) + 1 = 15 + 4 + 1 = 20.
For n = 2: 15 + 4(2) + 1 = 15 + 8 + 1 = 24.
For n = 3: 15 + 4(3) + 1 = 15 + 12 + 1 = 28.
Therefore, the first four terms of the sequence represented by the expression 15 + 4n + 1 are 16, 20, 24, and 28.
So, the correct option is "none of these" since none of the given choices match the calculated terms.
