Разность арифметической прогрессии:  d = a2 - a1 = -20 + 26 = 6

an > 0 - все положительные члены

a_1+(n-1)d textgreater  0\ \ -26+6(n-1) textgreater  0\ \ 6n textgreater  32\ \ n textgreater   frac{32}{6} approx5

При n = 6 будет первый положительный член, равный a_6=a_1+5d=-26+30=4

Relations between People

Most people believe that their relationships are not like others. They don't have

problems. These kinds of people also think that their partner won't cheat on them or

do anything wrong. But the truth is thalmost all relationships won't last forever.

A few reasons that relationships fall apart are when one partner cheats, they lose

interest in each other, lack of communication causes problems, if you try to change

someone and it backfires, and if you hide something you should have told the other

person and then they find out about it later. In relationships you can tell when you're

losing interest in each other. Some signs are that you don't talk much with each

other, you don't spend time together anymore instead he spends with your fric. ids

away from home.

Some signs to tell if the other person in the relationships is cheating another

starts to come home from work later than they usually do, they start to smell like

perfume that neither of you have, when you confront them about cheating and they

get all nervous and deny it, when you ask them why they ve been coming home late

from work and they makeup stupid excuses.

Sometimes they say they are going somewhere but when you phone to see if

they are there they aren't. If you're in relationship and the person does any of these

things, your relationship could be falling apart. In this kind of abusive relationship,

you should know it is time to leave.
