Find the sum of the counting numbers from 1 to 25 inclusive. In other words, if S = 1 + 2 + 3 + ... + 24 + 25, find the value of
Anastaziya [24]

Answer:

325

Step-by-step explanation:

You must have heard about Arithmetic Progressions (AP)

Arithmetic progressions are a series of numbers such that every successive number is the sum of a constant number and the previous number.

Our very own counting numbers form AP

For example :-

2 = 1 + <u>1</u>

3 = 2 + <u>1</u>

4 = 3 + <u>1</u>

The number in bold (1) is that constant number which is added to a number to form its successive number.

To find the sum of series forming AP, we use the formula :-

sum =  \frac{n}{2} \{ a  + a  _{n}  \}

here,

  • n is the number of terms
  • a is the first number of the series
  • an is the last number of the series

So we'll use all this information to find the sum of continuous numbers from 1 to 25 where 1 is the first term(a) and 25 is the last(an).

and n is 25

S  =   \frac{25}{2}\{ 1  +25\}

=  \frac{25 \times 26}{2}

= 25  \times 13

= 325

So, the value of S comes out to be 325.

Find the value of a in the parallelogram.
Rudiy27
First, turn both expressions into an equation
6a-4=<span>2a+<span>56
</span></span>---------------
Now solve
Subtract 2a from each side
<span><span>6a-4-</span>2a</span>=<span><span>2a+56-</span><span>2a
</span></span>4a-4=<span>56
</span>----------------------
Add 4 to each side
<span><span>4a-4</span>+4</span>=<span>56+4
</span><span>4a</span>=<span>60
</span>---------------------------
Divide each side by 4
4a ÷ 4 = 60 ÷ 4
a = 15
