-506.34

Step-by-step explanation:

(-345.5) + (-45) = (-390) + 65 = (-325.5) + (-76.49) = (- 401.99) + 14 = (-387.99) + (-160.75) = (-548.74) + 28 = (-520.74) + 16.40 = (-504.34) + (-2) = (-506.34)

I'm really sorry if I got the answer wrong

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
