This is confusing with the spaces in between the numbers. Can you post a screenshot of your question?

anonymous · Answer

@sammixboo what spaces, that's exactly how the question looks

sammixboo · Answer

Are you multiplying the numbers or what? Super hard to tell with nothing there

anonymous · Answer

I'm not sure actually, we must be but even on the actual assignment there isn't anything between them. We can just treat it as if we were multiplying them

sammixboo · Answer

Huh that is weird and just, not acceptable? Ok, but we are going to multiply then

The 4th answer? @nincompoop

nincompoop · Answer

how so?

sammixboo · Answer

I was wondering as well, because the parenthesis around the n in an is missing. It should be a(n) correct @nincompoop

Alright thank you

$\large a_n = -3 \times 4^{n - 1}   $
