The spacing is 6 1+6=7 7+6=13 13+6=19 19+6=25 so the missing number in the sequence is 13
That would be -5.

We could represent this in an Algebraic equation, where "x" is the missing number. If we write out the equation we will get:x + (-12) = 19. We simply add 12 to both sides.x + (-12) + 12 = 19 + 12.x = 19 + 12x = 31.When 31 must be added to -12 to obtain 19.
Missing you.
47, 40, 33, 26, 19, 12, and 5Assume this is an arithmetic sequence (It is formed by continually adding or subtracting the same number.)Because there are 7 missing numbers, there must have been 8 subtractions (the last one will produce the -2). The difference between the first and last terms is 54-(-2) = 54+2 = 56. Divide this by 8; the amount subtracted each time is 7. The missing numbers are 54-7 = 47, 47-7 = 40, ...
