Answer:
A
C
Explanation:
the functions that generate the sequence are;
1. 3 + 2n for n ≥ 0
n ≥ 0 means n starts from 0 till infinity
If n is substitute into the formula, it will give
3 + 2(0)
3+0=3
3 + 2(1)
3+2=5
3 + 2(2)
3+4=7
3 + 2(3)
3 +6=9
this formula is correct because it gives the arithmetic sequence
the second option is
-1 + 2n for n ≥ 0
n ≥ 2 means n starts from 2
if n is substituted into this formula, it gives
-1 + 2(2)
-1 +4=3
-1 +2(3)
-1+6=5
-1 + 2(4)
-1+8=7
-1 +2(5)
-1+10=9
this formula gives the arithmetic sequence which means the formula generated is correct
the other options are not right because it does not give the correct arithmetic sequence
Hope this helps!
