Answer:
explicit formula for an, the nth term of the sequence 19,24,29
Step-by-step explanation:
We need to Write an explicit formula for an, the nth term of the sequence 19,24,29
In the sequence the First term a₁= 19
Common Difference d= 5
The Formula used for explicit formula is:
Where d is common difference and n is nth term of sequence.
So, explicit formula for an, the nth term of the sequence 19,24,29

1) You know that a is 4/5 of b. This can be written as:
.
To find what b is equal to, multiply both sides by 5/4:
.
A is 5/4 B.
2) You know that a is 1/5 smaller than b. This can be written as:
.
To find b, just add 1/5 to both sides:
.
B is 1/5 bigger than a.
