Answer 2

It seems like you're trying to express the number 15 in terms of a specific pattern involving the number 2 and another variable "k". However, the expression you provided is a bit unclear. It seems you might be trying to say that 15 can be written as 2 times some value "k" plus 1, or in mathematical notation:

15 = 2k + 1

This equation is true when k equals 7. So, if k = 7, then:

15 = 2 * 7 + 1 15 = 14 + 1 15 = 15

If you could provide more context or clarify the pattern you're trying to represent, I'd be happy to assist you further!
