what are the explicit equation and domain for a geometric sequence with a first term of 3 and a second term of −9? an = 3(−12)n − 1; all integers where n ≥ 1 an = 3(−12)n − 1; all integers where n ≥ 0 an = 3(−3)n − 1; all integers where n ≥ 1 an = 3(−3)n − 1; all integers where n ≥ 0

i would say the third one.

step-by-step explanation: liner would mean in a line and the only one that doesn't look like it's even thinking about forming a line would be the third one

coins of silver or gold

step-by-step explanation:

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1
