Answer:
-7/ 48
Step-by-step explanation:
Given that:
Average change in water level per 3 years = - 7/16
This means the water level decreases by - 7/16 on average every 3 years
The change in water level after a year will be ;
-7/16 = 3
x = 1
Cross multiply ;
3x = - 7/16
Divide both sides by 3
x = -7/16 ÷ 3
x = - 7/16 * 1/3
x = - 7 / 48
Hence, water level will change by - 7/48 after a year.
The arithmetic sequence is 40, 47, 54 etc. In this case, the arithmetic difference is 7 and a1 being the first term is 40. Hence the arithmetic equation is an = 40 + 7*(n-1) where an is the nth term and n is an integer. Hence the answer to this problem is B.<span>a_n = 40 + 7(n − 1) where n ≥ 1 </span>
