K+29=9k-4 what is the variable

The varible is K, considering we are unsure as to what it means. If you are looking for what K equals :

K + 29 = 9K - 4

K - K +29 = 9K - K - 4

4 + 29 = 8K - 4 + 4

33 = 8K

K = 4.125

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 ! ~
