Question

In a sequence of numbers, a3=3, a4=7, a5=11, a6=15 a7=19.

Based on this information, which equation can be used to find the nth term in
the sequence?

Answer 1

B, an = 4n - 9

Explanation:

The sequence is for every time the exponent on a goes up one, the number that it equals to goes up by 4. So to find the nth term, we at 4 to n. I hope this helped! :)
