Step-by-step EXPLANATION:

Answer:

Here, The terms of given A. P. are=(-4),2,8,14,20,26............and so on.

Step-by-step explanation:

Here, As per our given question,

=Sum of the first 15 terms of given A. P. =570

=S15=570

=S15=n/2[2a+(n-1)×d (Where n=15)

=570=15/2[2a+(15-1)×d

=570=15/2(2a+14d)

=570=(15/2×2a)+(15/2×14d)

=15a+105d=570

=a+7d=38 -(1st)eq. (As all numbers are divisible by 15)

Now, As given in question,

=Twelfth term of this A. P.=62

=T12=a+(n-1)×d (Where n=12)

=62=a+(12-)×d

=62=a+11d

=a+11d=62 -(2nd)eq.

Now, As we would apply ELIMINATION method to both equations, Here both equations have same sign (+), So, here we would subtract EQUATION 2 from 1,

= a+7d=38

=-(a+11d=62)

After subtracting, we get,

=7d-11d=38-62

=(-4d)=(-24)

=4d=24 (As minus is on both sides, so it gets cancelled)

=d=24/4

=d=6

Now, by putting the value of d in eq. 1,we get,

=a+7×(6)=38

=a+42=38

=a=38-42

=a=(-4)

So, Now, As we have,

First term(a) of the A. P.=(-4)

Common difference(d) of the A. P.=6

So, Now its sequence or its terms are,

=a, (a+d), a+2d, a+3d, a+4d, a+5d...........

.. (And continue it like this for more terms)

=(-4),(-4+6),(-4+2×6),(-4+3×6),(-4+4×6),(-4+5×6)......

=(-4),2,8,14,20,26............ (Answer).

Thank you.

<P>

Historically, mathematics is Greek. Pythagoras, Socrates, Archimedes, Aristotle, Plato, all were greek. Mathematics is deeply rooted in Greek.

The original sum sign was a greek LETTER, as is the sign for “change in,” or delta, the standard sign for an angle, theta, and more.

We could have changed them to the English alphabet, yes, but that could pose some problems. The biggest example is pi, which is, of course, Greek. If we just used “p,” it could be MISTAKEN as a variable.

Having these special MEANINGS be represented by Greek VARIABLES can help distinguish them from variables, but honestly, the biggest reason is, why change it? It’s historical, it works, and that’s that.

=135

similarly,

x×α

=180.

similarly

=243−3

=240.

Taking HCF OF 135, 180 & 240.

∴ HIGHEST common factor =5×3

=15.

∴ greatest no which will DIVIDE 138,183 &

243 and leaves remainder as '3' = 15

Answer:

Number of Sides = 36

[MARK THE ANSWER AS BRAINLIEST]

Step-by-step explanation:

The formula for calculating the sum of INTERIOR angles is ( n − 2 ) × 180°

= 170° × Number of SIDE of Polygon (n)

⇒ ( n - 2 ) × 180° =  170° × n

⇒ 180n - 360 = 170n

⇒ 180n - 170n = 360

⇒ 10n = 360

⇒ n = 360/10 = 36
