Show you solution. List the terms that complete a possible pattern in each of the following:
a)38,33,28,23,18,_,_,_
b)640,320,160,80,_,_,_
c)7,8,15,23,38,_,_,_

  • math -

    a) What number is subtracted from each number to get the next number?

    b) What number is divided into each number to get the next number?

    c)
    7 + 8 = 15
    8 + 15 = 23
    23 + ? = 38

  • math -

    a) 5 is subtracted from each so, it should be 13,8,3
    b)2 is divided into each number so, it should be 40,20,10
    c)23+15=38
    61,99,160 Not sure(?)

  • math -

    Right on all problems! :-)
