Question

The nth term of a sequence is 2n + 5
Is 32 a term in the sequence?

Answer 1

To find out if 32 is a term in the sequence, we can substitute n = (32-5) / 2 = 13.5 into the formula and check if we get an integer value.

2(13.5) + 5 = 27 + 5 = 32

Since we get 32, it means that 32 is a term in the sequence.
