Question

Find the 10th term in the sequence given by b(n) = -5 + 9 (n-1)

Answer 1

The expression of the sequence:

`b(n)=-5+9(n-1)`

We need to find the 10th term

Substitute n = 10 in the expression

`\begin{gathered} b(n)=-5+9(n-1) \\ b(10)=-5+9(10-1) \\ b(10)=-5+9(9) \\ b(10)=-5+81 \\ b(10)=76 \end{gathered}`

So, 10th term of the sequence is 76

Answer: 76
