What is the relation between any two consecutive terms?
Pattern: Arithmetic
Next Term: a_5= 54
Rule for the nth Term: a_n= n4
We can see that the difference between any two consecutive terms is always 14. Therefore, we have an arithmetic sequence with a common difference of 14. To find the 5th term, we will add 14 to the 4th term. a_5=4/4+ 1/4=5/4 Finally, considering that we have an arithmetic sequence with a first term of 14 and a common difference of 14, we can write its rule. a_n= a_1+(n-1) d ⇓ a_n= 1/4+(n-1) 1/4 [0.5em] a_n=n/4
