פעולות על סדרה הנדסית – שתי סדרות – מדרגה 2

פעולות על סדרה הנדסית - שתי סדרות

מדרגה 2

המספרים: $3, 12, 48$ הם שלושה איברים בסדרה הנדסית.

$a,b,c$ הם שלושה איברים כך ש: $3,a,12,b,48,c$ היא סדרה הנדסית.

מצאו את האיברים $a,b,c$
מה ניתן לומר על האיברים $a,b,c$ ?

אחרי שפתרתם את הבעיות במדרגה 2, פתרו את בעיית המטרה.
או, במידת הצורך, פתרו את הבעיות במדרגה 3.
