(The answer is in the bottom of the picture)
The answer to this problem is the letter "A" which is "Multiply by 3, then add 2"
and can be written a N = 3n + 2
At first, we have initial value such n = 1
Then the second value is:
N = 3*1 + 2
N = 5
The third value is:
N = 3*5 + 2
N=17
The next values are:
N = 3*17 + 2
N= 53
The letter "A" is the inductive reasoning to the given sequence.
Answer:
X=20
you subtract 15 from 75 to get 60 then divide 60 by 3 to get 20
Can you post the rest of the info? x
