The first four terms of a pattern are given below. 4, -1, -6, -11, ... What is the eighth term of the pattern?
zavuch27 [327]

Answer:

  -31

Step-by-step explanation:

If we continue to subtract 5 from the previous term, the sequence continues ...

  4, -1, -6, -11, -16, -21, -26, -31, -36, ...

The 8th term is -31.

_____

This is an arithmetic sequence with first term a1 = 4 and common difference d = -5. The general term (an) of such a sequence is ...

  an = a1 +d(n -1)

Filling in the values for this sequence, the general term is ...

  an = 4 -5(n -1)

Then the 8th term is ...

  a8 = 4 -5(8 -1) = 4 -35

  a8 = -31
