Question

in a sequence, the first term is 12 and the common differences 4. What is the 10th term of the sequence?

Answer 1

Answer: 48

Step-by-step explanation

The nth term is
`a_n = 12 + 4(n-1)` based on the template
`a_n = a_1 + d(n-1)`

Plug in the value n = 10 to determine the 10th term.

`a_n = 12 + 4(n-1)\\\\a_(10) = 12 + 4(10-1)\\\\a_(10) = 48`

A spreadsheet can be used to verify this answer is correct.
