Which term of the AP:3,15,27, 39,.....will be 132 more than its 54th term

horsena [70]

Answer:

n=65th term

Step-by-step explanation:

AP:3,15,27,39......

From the AP

a=3

a+d=15

a+2d=27

3+d=15 (1)

3+2d=27 (2)

Subtract (1) from (2)

We have,

2d-d=27-15

d=12

54th term=a+(n-1)d

=3+(54-1)12

=3+(53)12

=3+636

=639

The term is 132 more than the 54th term

132+54th term

=132+639

=771

Find the term

771=a+(n-1)d

771=3+(n-1)12

771-3=12n-12

768=12n-12

768+12=12n

780=12n

n=780/12

=65

n=12

The term which is 132 more than the 54th term is the 65th term

<h2>Explanation:</h2>

Hello! here we need to match the statements on the left-hand side to the reasons on the right-hand-side.

So this is as follows:

Statements: Reasons:

Segment Addition Postulate $AB+BC=AC$

Substitute the given values $5x+1+15=7x$

Simplify $5x+16=7x$

Subtract 5x from both sides $16=2x$

Divide both sides by 2 $16/2=2x/2$

Simplify $AC=7x$

Substitute 8 for x $AC=7(8)$

Simplify $AC=56$

So what we did here is to find the measure of segment AC by finding the x-value first. In other words, we have proven that AC = 56 by following logical arguments organized in an structured manner.
