Qo‗shni o‗lchamlar farqining naminal o‗lchamlar qatoriga nisbyuatan o‗zgarish
qonuniyati bo‗yicha geometrik progressiyadan foydaianish ancha qulay (7.1.1.3-
rasm).
7.1.1.3-rasm
Qo‗shni o‗lchamlar farqining nominal o‗lchamlar qatoriga bog‗liqligi: 1 –
arifmetik progressiya; 2 – pog‗onali arifmetik progressiya, 3–geometrik progressiya.
