Use Gauss's approach to find the following sums (do not use formulas) a 1+2+3+4 998 b. 1+3+5 7+ 1001 a The sum of the sequence i

valkas [14]

Answer:

(a) 498501

(b) 251001

Step-by-step explanation:

According Gauss's approach, the sum of a series is

$sum=\frac{n(a_1+a_n)}{2}$ .... (1)

where, n is number of terms.

(a)

The given series is

1+2+3+4+...+998

here,

$a_1=1$

$a_n=998$

$n=998$

Substitute $a_1=1$ , $a_n=998$ and $n=998$ in equation (1).

$sum=\frac{998(1+998)}{2}$

$sum=499(999)$

$sum=498501$

Therefore the sum of series is 498501.

(b)

The given series is

1+3+5+7+...+ 1001

The given series is the sum of dd natural numbers.

In 1001 natural numbers 500 are even numbers and 501 are odd number because alternative numbers are even.

$a_1=1$

$a_n=1001$

$n=501$

Substitute $a_1=1$ , $a_n=1001$ and $n=501$ in equation (1).

$sum=\frac{501(1+1001)}{2}$

$sum=\frac{501(1002)}{2}$

$sum=501(501)$

$sum=251001$

Therefore the sum of series is 251001.

Solve for X and Y <br><br> I will mark brainliest !!

viktelen [127]

Answer:

X=24, Y=7

Step-by-step explanation:

We use the concept of similarity.

By observing the figure, we notice that the hypotenuse is 50, and the hypotenuse of the smaller triangle is 25.

That means the hypotenuse of the larger triangle is double the hypotenuse of the smaller triangle. Meaning, the other sides of the larger triangle would be double the smaller sides of the smaller triangle.

We already have the sides of the larger triangle, divide them by two to get x and y.

X = 48/2 = 24

Y = 14/2 = 7
