Examine the following sequence 1, 4, 9, 16, 25…. Why is 36 the next number in the sequence? Because the pattern is:

1 answer:

7 0

You are adding consecutive odd numbers to the number before. Starting with 1, add 3 to get 4. Add 5 to 4 to get 9. Add 7 to 9 to get 16, add 9 to 16 to get 25, add 11 to 25 to get 36. Trying to figure out how to write that as a recursive rule...

Eric’s average income for the first 4 months of the year is $1,450.25, what must be his average income for the remaining 8 month

UNO [17]

Answer:

$1946

Step-by-step explanation:

His average for the first four months

= $1,450.25

So he earned 4*$1,450.25

= $5801 for the first four months.

Then for the year his average is $1,780.75.

So he earned $1,780.75*12 for the year.

=$ 21369

So the amount he earned for the remaining 8 months was 21369-5801

= $15568

The average for the 8 Months= 15568/8

= $1946

PLSSS HELP What is the formula for the following arithmetic sequence? -2, 3, 8, 13, ... an = -2n + 3 an = -2n + 7 an = 5n + 3 an

san4es73 [151]

Answer:

an = 5n -7

Step-by-step explanation:

Try the offered formulas with n= 1 and see which gives you the first term of the sequence.

an = -2n +3

-2(1) +3 = 1 . . . . not -2

an = -2n +7

-2(1) +7 = 5 . . . . not -2

an = 5n +3

5(1) +3 = 8 . . . . not -2

an = 5n -7

5(1) -7 = -2 . . . . this is the formula you want

_____

If you recognize the common difference of the sequence to be 5, then you can automatically eliminate any formulas that don't contain 5n.
