If a_1=5a 1
​
=5 and a_n=a_{n-1}+4a
n
​
=a
n−1
​
+4 then find the value of a_5a
5
​
.

Step-by-step explanation:

Arithmetic sequence:

In an arithmetic sequence, the difference between consecutive terms is always the same, and this difference is called common difference.

The nth term of an arithmetic sequence is given by:

In which is the first term and d is the common difference.

In this question:

. So

Find the value of a_5

So

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
