Question

For the sequence an=3n-5 what is the value of a10

Answer 1

Answer: The value of
`a_(10)=25`

Explanation:

The given sequence :
`a_n=3n-5` .

To find the value of
`a_10` , need to substitute the value n=10 in the above equation , we will get

`a_(10)=3(10)-5`

Open Parenthesis ,

`a_(10)=3*10-5`

Solve product ,

`\Rightarrow\ a_(10)=30-5`

Solve subtraction,

`\Rightarrow\ a_(10)=25`

Therefore , the value of
`a_(10)=25`

Answer 2

Answer: The required value of
`a_(10)` is 25.

Step-by-step explanation: We are given a sequence whose n-th term is given as follows :

`a_n=3n-5.`

We are to find the value of
`a_(10).`

To find the value of
`a_(10).`, we need to put n = 10 in the given expression.

So, substituting n = 10 in the given expression, we get

`a_(10)=3* 10-5=30-5=25.`

Thus, the required value of
`a_(10)` is 25.
