If we collect experimental data on alcohol consumption from the same 100 individuals before and then after a course on the dange

The formula that describes the sequence is

Step-by-step explanation:

The nth-term formula for a geometric sequence is , where

• a represents the first term of the sequence
• r signifies the common ratio between any two consecutive terms
• =

∵ The sequence is , -4, -24, -144,.......

∵ The first term is

∵ The second term is -4

∴

∵ The third term is -24

∴

∵ The fourth term is -144

∴

∵   = =   = 6

∴ There is a consistent ratio between two consecutive terms

∴ The sequence qualifies as a geometric sequence

∵ The formula for the nth term of the geometric sequence is

∵ a =

∵ r = 6

∴ The equation for the sequence is

The formula that can be employed to outline the sequence is

Answer: 21

Step-by-step explanation: essentially

Answer:

1.4×10⁻⁵=0.000014

Step-by-step explanation:

Since the exponent of the 10 term is negative, shift the decimal point to the left by 5 positions;

1.4×10⁻⁵=0.000014
