Question

The line graph shows Jeff's weight, in kilograms, during the first five months of the year. If the trend continues, which is the BEST prediction for Jeff's weight in June?
73 kg      
79 kg
82 kg
88 kg

Answer 1

so it is increasing first by 9kg the 6kg, my guess is that it will increase and it will be by 3 kg, but this is just a guess his weight will be 91kg.

Answer 2

His wait will most likely be 91


73 to 79 will be 6
79 to 82 will be 3
82 to 88 will be 6
88 to 91 will be 3

so the answer is 91
