Find the 10th term in a sequence whose general term is an = n2 – 8. Question 7 options: A) 92 B) 108 C) 12 D) 113

Respuesta :

Answer:

92

Step-by-step explanation:

The 10th term in a sequence whose general term is [tex]a_n = n^2 - 8[/tex] will be 92. so option A is correct.

What is arithmetic sequence?

An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.

If the initial term of a sequence is 'a' and the common difference is of 'd', then we have the arithmetic sequence as:

a, a + d, a +  2d, ... , a + (n+1)d, ...

Its nth term is

T_n = a + (n-1)d

(for all positive integer values of n)

And thus, the common difference is

T_{n+1} - T_n

for all positive integer values of n

We need to find the 10th term in a sequence whose general term is

[tex]a_n = n^2 - 8[/tex].

So, the 10th term is (10)²- 8

= 100 - 8

= 92

Therefore, the 10th term in a sequence whose general term is

[tex]a_n = n^2 - 8[/tex] will be 92. so option A is correct.
