Question

Given the following arithmetic sequence; starting with 107, which term has a value of -61?

107, 101, 95...-61

(show steps pls)

Answer 1

Explanation:

The pattern of this sequence is : From a term, we minus 6 to get to the next term

107 - 6 = 101
101 - 6 = 95
So on and so on.

The difference between 107 and -61 is : 107 - (-61) = 168

Everytime we go to the next term, we get 6 units closer to -61

So, -61 will be the 168 : 6 = 28th term of this arithmetic sequence.
