X, 2X + 11 and 4X - 3 are consecutive terms of an arithmetic sequence. Find the constant difference between terms. Give a formul

Anna007 [38]

Common difference between the terms is 36

Formula for nth term is $a_n=36n-11$

27th term is 961

Given :

X, 2X + 11 and 4X - 3 are consecutive terms of an arithmetic sequence

To Find:

We need to find the constant difference between the given terms and also find the nth term . Also find the 27th term .

To find the difference , we need to take the difference of consecutive terms

$2x+11-x=x+11\\\\4x-3=(2x+11)= 4x-3-2x-11=2x-14$

Both the common differences are equal

$x+11=2x-14\\Solve \; for \; x\\Subtract \; x\\11=x-14\\Add \; 14\\x=25$

First term is 25

second term is 2(25)+11=61

Difference is 61-25=26

Common difference = 36

Use nth term formula is

$a_n=a+(n-1)d\\a=25 (first term )\\d=36\\a_n=25+(n-1)(36)\\a_n=25+36n-36\\a_n=36n-11$

To find 27th term , replace n with 27

$a_{27}=36(27)-11=961$

Brums [2.3K]

Answer:

1) It would be about a 55% increase. 2) It would be about a 79% increase

Step-by-step explanation:

I used process of elimination to figure out how much of a percentage would be needed by just multiplying 210 by different percentages until I found the answer.

Sorry I don't have like a definite formula or anything for you to figure these questions out... I hope someone else answers with a more definite answer!
