The answer for 2^-3 is 1/8
QUE :
75 - [5 + 3 of (25 - 2 × 10)]
= 75 - [5 + 3 of ( 25 - 20)]
= 75 - [5 + 3 of 5]
= 75 - [5 + 15]
= 75 - 20
= 55

Answer:
B
Step-by-step explanation:
Substitute the value of (2,1) into the equations, and you find that only B works.
The given sequence is an arithmetic sequence beacuse there is a common difference between consecutive terms. We can determine this by subtracting the consecutive terms as shown below
Common difference, d = 8 - 3 = 13 - 8 = 18 - 13 = 5
The explicit equation for an arithmetic sequence is written as
an = a1 + d(n - 1)
The first term, a1 = 3
n is the number of terms
d is the common difference aand it is 3
By substituting these values into the equation, the explicit formula for this sequence is
an = 3 + 5(n - 1)
