Find the 4th term in the sequence

Answer 1

[AI-generated answer — Bot GPT 3.5]

To find the 4th term in the sequence, we can use the recursive formula given:

a(1) = -2
a(2) = a(1) - 5 = -2 - 5 = -7
a(3) = a(2) - 5 = -7 - 5 = -12
a(4) = a(3) - 5 = -12 - 5 = -17

Therefore, the 4th term in the sequence is -17.
