Parse the formula in the image first Then based on the formula, answer "what's the 4th term in the sequence?"
The formula is: (b(1) = 15) (b(n) = b(n-1) \cdot (-3))
(b(1) = 15) (b(2) = b(1) \cdot (-3) = 15 \cdot (-3) = -45) (b(3) = b(2) \cdot (-3) = -45 \cdot (-3) = 135) (b(4) = b(3) \cdot (-3) = 135 \cdot (-3) = -405)
So the 4th term in the sequence is -405.
