n ?

Consider the sequence in the table. Which formula gives the number that would be in the nth position of the sequence?

A) 5n

B) 10n

C) n + 5

D) n - 5

Answer 1

Per value of n, 5 is being added to arrive at the new number.

When n = 1, the number is 6.

When n = 4, the number is 9.

Because of this, we know the formula would be n + 5.

The correct answer is C.
