It could be tn = n2 + 6 for n = 1,2,3,...
It is not a rule as such; those number are the first 10 prime numbers.
10 + 10 + 10 + 10 + 15 + 15 + 0 = 7070/7 = 10Average = 10
The rule for the pattern is y=x+2. That rule is in the table format in which it would originally be in, but the worded rule would be 'It increases by 2 each time'.
It is: -2 because -2-15 = -10-7 => -17 = -17
15/10 + 7/100 = 1.57
3 is the answer
The pattern will be +2, +3, +4, +4
Add 3 each time
You see the differences between the integers is 10,9,8.... so your difference for the next integer is 7
One possible rule is: Un = (243n5 - 4210n4 + 27225n3 - 60830n2 + 106452n - 45960)/120 for n = 1, 2, 3, etc
is this question number 10? 4n - 1 creates the pattern 3, 7, 11, 15, 19, etc.
Each successive number is the sum of the previous number times 2, plus 1.
7/10 of 15 = 15*7/10 = 21/2
7 and 10/15 + 2 and 12/15 = 9 and 22/15 = 10 and 7/15
It is not a rule as such; those number are the first 10 prime numbers.
7+7+7+14+15=50 50/5=10 Your answer is 10.
8/15 = 0.53 7/10 = 0.70 No they are not
