Solve pattern 66 73 13 21 52 _ 10 20

1 answer:

4 0

The answer would be 61. First, if you are trying to figure out the pattern. You must subtract the second number with the first then fourth number with the fifth and so on, you get.

73 minus 66 equals 7.
21 minus 13 equals 8.
XX minus 52 equals x.
20 minus 10 equals 10.

Basing on the pattern of the set of numbers, x will equal 9, To get this you must do 52 and 9 which will equal 61.

HACTEHA [7]

So the equation for this would be y= 90x where y would be the distance in feet covered in x seconds and x would be seconds. So to find out the distance covered in 25 seconds you would plug in 25 for x.

y= 90(25)
y= 2250

So to answer the question you would say that the cheetah would cover 2,250 feet in 25 seconds.
