6+5•2+15
10+6
16+15
The answer is: 31
Hope this helps
Answer:
a degree is the highest exponent
so all of the have an exponent of 1 which means all of the have the same exponent
all the numbers are degrees of this trinomial I bealive
Step-by-step explanation:
Given sequence is: - 3, 5, 13...
Here first term a = - 3
common difference d= 5-(-3)=13-5=8
Hence, it is in A. P.
Nth term of an AP is given as:
![t_n = a + (n - 1)d \\ \\ \therefore \: t_n = - 3 + (n - 1) \times 8 \\ \\ \therefore \: t_n = - 3 + 8n - 8 \\ \\ \huge \red{ \boxed{\therefore \: t_n = 8n - 11}}](https://tex.z-dn.net/?f=t_n%20%3D%20a%20%2B%20%28n%20-%201%29d%20%5C%5C%20%20%5C%5C%20%20%5Ctherefore%20%5C%3A%20t_n%20%3D%20%20-%203%20%2B%20%28n%20-%201%29%20%5Ctimes%208%20%5C%5C%20%20%5C%5C%20%5Ctherefore%20%5C%3A%20t_n%20%3D%20%20-%203%20%2B%208n%20-%20%208%20%20%5C%5C%20%20%5C%5C%20%20%5Chuge%20%5Cred%7B%20%5Cboxed%7B%5Ctherefore%20%5C%3A%20t_n%20%3D%20%208n%20-%20%2011%7D%7D)
Which is the required formula for the given sequence.
answer:
put a picture of the question, it is easier to understand that way.
