13×15 + 15×12 + 5×15 + 12×5 (two triangles of same base/height so don't divide by 2)

=195 + 180 + 75 + 60

alright well the answers to your question is

2xy/9 hope this have a nice day : )

step-by-step explanation:

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
