Answer: 989.172
Step-by-step explanation:
•For Denominator with Roots , we need to multiply it with itself to the both the numerator and denominator.
Then , Do as follows:
Answer:
Step-by-step explanation:
Given is the sequence 3, 8, 13, 18, 23, ….:
We find that this is a geometric sequence with each term added with 5 to the previous term
Hence recursive formula is ![a_n =a_{n-1} +5](https://tex.z-dn.net/?f=a_n%20%3Da_%7Bn-1%7D%20%2B5)
Non recursive formula:
![a_n =a_{n-1} +5=a_{n-2} +2(5)\\=a_{n-3} +3(5)-...\\=a_{n-(n-1)} +5(n-1)\\=a_1+(n-1)5\\=3+5n-5\\=5n-2](https://tex.z-dn.net/?f=a_n%20%3Da_%7Bn-1%7D%20%2B5%3Da_%7Bn-2%7D%20%2B2%285%29%5C%5C%3Da_%7Bn-3%7D%20%2B3%285%29-...%5C%5C%3Da_%7Bn-%28n-1%29%7D%20%2B5%28n-1%29%5C%5C%3Da_1%2B%28n-1%295%5C%5C%3D3%2B5n-5%5C%5C%3D5n-2)
iii) Start with 3.
Add 5 and write as 2nd term
Take the resulting term and add 5 and mark as 3rd term
Repeat this m times.
Answer: it is -1
Step-by-step explanation:
5*5x=25x
5*3=15
25x+15=-10
25x= -10-15
25x= -25
X=-25/25
= -1
