Answer:
Third option. I am sure it!
Step-by-step explanation:
Mark other guy brainliest. He's a great answer and he helped me before
Rounding numbers means you change the number to a closer, easier number. For example if you want to round 56 to the nearest tenth, it would round to 60.
Estimating numbers is when you guess numbers. For example, if you want to estimate the measure used to measure a bed, i would estimate feet.
I hope this helped:))
I’m not sure but I think
F (2, -1)
G (1, -3)
H (-3, -1)
Given:
The recursive formulae are:
(a) 
(b) 
To find:
The explicit equation.
Solution:
A recursive formula of an arithmetic sequence is
and f(1) is the first term.
Where, d is the common difference.
The explicit formula is

where, a is first term and d is common difference.
(a)
We have,

Here, first term is 8 and common difference is -2. So, the explicit formula is



Therefore, the explicit formula is
.
(b)
We have,

Here, first term is 0 and common difference is 5. So, the explicit formula is


Therefore, the explicit formula is
.
