What is the explicit formula for the arithmetic sequence 4/5, 29/30, 17/15, 13/10. answer is d on edg an = 4/5 + 1/6(n-1)

Step-by-step explanation:

The explicit formula is given by:

Where a is the first term (4/5) and d is the common difference (the difference is any 2 terms). So to find d:

29/30 - 4/5

29/30 - 24/30

5/30

1/6

d = 1/6

Now putting them into the formula:

The last answer choice is right.

take angle U as reference angle

using sine rule

sin U=opposite/hypotenuse

sinU=42/42

sin U=1

sin 90=1

therefore the value of U is 90 degree
