There seem to be some missing terms in the sequence. Assuming it is a four-term sequence, one possible solution is:
The geometric mean of 6 and 162 is sqrt(6*162) ≈ 36.

find Sn for the arithmetic series a1=16,an=48,n=6
We can use the formula for the sum of an arithmetic series:
Sn = n/2 * (a1 + an)
Plugging in the given values:
Sn = 6/2 * (16 + 48) = 3 * 64 = 192
Therefore, the sum of the arithmetic series is 192.
Sn = n/2 * (a1 + an)
Plugging in the given values:
Sn = 6/2 * (16 + 48) = 3 * 64 = 192
Therefore, the sum of the arithmetic series is 192.
