  6. Arifmetikprogressiyata’rifi: Ta’rif. Agar a₁, a₂,…, an… sonliketma-ketlikdabarcha natural nlaruchun an+1= an+ d (bunda d – biror son) tenglikbajarilsa, bundayketma-ktlikarifmetikprogressiyadeyiladi. an+1- an = d

  7. Arifmetikprogressiyata’rifigako’ra: a2 = a1+d a3 = a2+d=a1+2d a4 = a3+d=a1+3d vah.k. an =a1 + (n-1)d

  8. Misollar 1) Sonlarning 1,2,3,4 …, n, … natural qatoriarifvetikprogressiyanitashkilqiladi. Bu progressiyalarningayrmasi d=1. 2) Butunmanfiysonlarning -1, -2, -3, …, - n, … ketma-ketligiayirmasi d = -1 bo’lganarifmetikprogressiyadir. 3) 3, 3, 3, …, 3, … ketme-ketlikairmasi d= 0 bo’lganarifmetikprogressiyadaniborat.

  9. an = Masala an+1 an an-1 a3 a2 a1

  10. Mustahkamlashgadoirsavollar: 1) Arifmetikprogressiyagata’rifbering. 2) Arifmetikprogressiyaningayirmasidegandanimanitushunasiz? 3) Arifmetikprogressiyaningn – hadinitopishformulasiniayting. 4) O’rtaarifmetikqiymatdebnimagaaytiladi? 5) Ketma –ketlikning 1 va 3-hadlari ma’lumbo’lsa, 2-had qandaytopiladi?
