Acertain arithmetic sequence has the following explicit formula for the nth term: an = 3 + (n – 1)(8) the same sequence has the following recursive formula: an = an – 1 + what number belongs in the blank space in the recursive formula

Missing number = 8 in the recursive formula

Step-by-step explanation:

The explicit formula for an arithmetic sequence is

Here a = first term of the sequence

n = nth term

d = common difference

Explicit formula for an arithmetic sequence is given in the question

So the first term of the sequence is a = 3

and common difference d = 8

Now the recursive formula of the same sequence will be

Since d = 8 for the sequence.

Therefore the missing number is 8 in the recursive formula.

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.
