Arrange the summation expressions in increasing order of their values

Svetradugi [14.3K]

Sum of n terms = a1 (r^n-1/ (r-1)

Sum of first one = 3 * (4^5 - 1) / 3 = 1023
.. 2nd = 5 * (6^2 - 1) / 5 = 35
.. 3rd = 5 ^4 - 1 / 4 = 156
.. 4th = 4 * (5^4 - 1) / 4 = 624

So in increasing order its 2nd, 3rd, 4th and first.

In a certain year, the average e-mail user sent or received 111 e-mails each day. The number of e-mails received was 3 more than

Ludmilka [50]

Answer:

Number of sent mail = 36

Number of received mail = 75

Step-by-step explanation:

Let,

x be the number of mails sent

y be the number of mails received

According to given statement;

x + y = 111 Eqn 1

y = 2x + 3 Eqn 2

Putting value of y from Eqn 2 in Eqn 1

x + 2x + 3 = 111

3x = 111 - 3

3x = 108

Dividing both sides by 3

$\frac{3x}{3}=\frac{108}{3}\\x = 36$

Putting x = 36 in Eqn 2

y = 2(36) + 3

y = 72 + 3 = 75

Hence,

Number of sent mail = 36

Number of received mail = 75
