-26.
You are subtracting each number in the series by 25 to find the next number.
So 49 - 25 = 24
24 - 25 = -1
And -1 - 25 = -26
The next number would then be -26 - 25 = -51
etc...
The next number is 49+8 = 57
25, 36, 49, 64 are the next numbers.
The next two square numbers after 30 are 36 and 49
This sequence is the squaring of the numbers 1, 3, 5, and 7. The next number is 9^2 = 81.
The pattern of these numbers is the square numbers. Therefore, following 42 = 16 comes 52 = 25, 62 = 36, 72 = 49.
24 and 25, which are (49-1)/2 and (49+1)/2
They are: 36 and 49
38.25 is the average The way you do it is...add all the numbers, then divide that number by the numbers of numbers you just added. 65+49+24+15=153 153/4=38.25
36 and 49
Yes, they are relatively prime.
24+25=49
The next number is 0
