Question

Write an explicit formula for the sequence 7, 2, –3, –8, –13, find the 14th term

Answer 1

The 14th term is equal to -44.

y = 12 - 5x

The sequence can be represented by this function.

Each term is being subtracted by 5.

Using this function we can find the 14th time.

y = 12 - 5(14)

y = 12 - 56

y = -44
