Which value represents the first two terms of the sequence a1=2 and an=-3 (an-1) ^2?

I'm not really sure what you're asking, but if you want to calculate the first two terms of the sequence after a1, then here's the answer:

If a1=2, then a2 = - 3 (a1 - 1) ^2 = - 3 (2-1) ^2 = - 3 * (-1) ^2 = - 3*1 = - 3.

Then, a3 = - 3 (a2 - 1) ^2 = - 3 (-3-1) ^2 = - 3 (-4) ^2 = - 3*16 = - 48.

I'm sorry if this is not what you wanted.
