Common difference between the terms is 36
Formula for nth term is
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
Both the common differences are equal
First term is 25
second term is 2(25)+11=61
Difference is 61-25=26
Common difference = 36
Use nth term formula is
To find 27th term , replace n with 27

We have that
, which means
reduces to
when
, or reduces to
when
.
So we can expand the summation as
Notice that the 10 contributes a total of 30 from the first sum, and -30 from the second sum, so those terms cancel, leaving us with
The Addition Property of Equality
Answer:
<h2>135</h2>
Step-by-step explanation:
<h2>15 <em>multiplied by</em> -9= -135</h2><h2>then -135 <em>multiplied</em> <em>by</em> -1 = 135 </h2><h2>the negative cancels because two negatives are being multiplied . </h2><h2>answer is 135 </h2><h2 />
