Answer:
Step-by-step explanation:
we have 105 marbles
number of blue marbles= x
green marbles= x+25
x+x+25=105
2x=105-25
2x=80
x=40 blue marbles

well, we know the common difference is -3, to go from the 4th term to the 8th term, we need to add "d" 4 times or namely 3+4(-3), likewise to go from the 13th term to the 19th term we have to add "d" 6 times, or namely -24 + 6(-3).
