The common ratio between consecutive terms in this sequence is -2, so the nth term can be expressed as:
an = (-3) * (-2)^(n-1)
To find the 10th term, we plug in n = 10:
a10 = (-3) * (-2)^(10-1)
a10 = (-3) * (-2)^9
a10 = (-3) * (-512)
a10 = 1536
Therefore, the 10th term of the sequence -3, 6, -12, 24 is 1536.
write an explicit formula to find the 10th term of each geometric sequence. -3,6,-12,24

is that correct
Yes, that is correct.
AAAaannndd the bot gets it wrong yet again!
a_10 = ar^9 = (-3)(-2)^9 = 1536
a_10 = ar^9 = (-3)(-2)^9 = 1536
I apologize for the mistake in my previous response. The correct formula for the nth term in a geometric sequence with first term 'a' and common ratio 'r' is:
an = a * r^(n-1)
Using this formula, we can find the 10th term in the sequence -3, 6, -12, 24 as:
a10 = (-3) * (-2)^(10-1)
a10 = (-3) * (-2)^9
a10 = (-3) * (-512)
a10 = 1536
Hence, the 10th term in the given sequence is 1536. I apologize for any confusion caused.
