Answer:
65, 78, 91, 104
Explanation:
To find out how to get the next 4 multiples of the same number, you would subtract the numbers you already have from each other.
You would take 52 - 39, and you would get 13.
Then you would take 39 - 26 and get also get 13.
See the pattern?
52 - 39 = 13
39 - 26 = 13
26 - 13 = 13
Each of the numbers subtracted from each other equals 13, that means to get the next set of numbers you would add 13 on to the previous number.
52 + 13 = 65
65 + 13 = 78
78 + 13 = 91
91 + 13 = 104
Hope this helps! :)
