I want to typeset some sequences/progressions. I'm trying (in math mode):
x_1 = 2.3, x_{n+1} = x_n - 0.7 (n = 1, 2, 3, \ldots)
but the spacing is much too tight when this is typeset. For example LaTeX interprets the term showing the progression of n as a coefficient of -0.7. I understand why this is happening but don't know how to stop it.
What is the correct way to typeset sequences/progressions in LaTeX?

to add a bit more space:$x_1 = 2.3,\, x_{n+1} = x_n - 0.7\, (n = 1, 2, 3, \ldots)$
