To find the value of b5 using the given pattern, we need to determine the common difference and then continue the pattern.

The common difference is found by subtracting each consecutive term from the previous term.

d1 = b2 - b1 = -3 - 3 = -6
d2 = b3 - b2 = 12 - (-3) = 15
d3 = b4 - b3 = b5 - 12

Since the common difference is increasing by 3 each time, we can determine the value of d4 by adding 3 to d3:

d4 = 12 + 3 = 15

Therefore, the common difference is 15.

To find b5, we add the common difference to the previous term:

b5 = b4 + d4 = 12 + 15 = 27

Therefore, b5 = 27.
