Acertain arithmetic sequence has the following explicit formula for the nth term: an = 4 + (n - 1)(7) the same sequence has the following recursive formula: an = an-1 + what number belongs in the blank space in the recursive formula?

Step-by-step explanation:

We know that the nth term in Arithmetic sequence is given by :-

..................(1)

Given: A certain arithmetic sequence has the following explicit formula for the nth term:

.............................(2)

When we compare (1) and (2), we get

Also, the recursive formula in A.P. can be written as

Therefore, The same sequence has the following recursive formula:

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
