Odpowiedź:
a1 = 4 a2 = - 6 a3 = 9
więc q = a2 : a1 = - 1,5
I sposób :
a4 = 9*(-1,5) = - 13,5
a5 = -13,5 *(- 1,5) =20,25
S5 = 4 - 6 + 9 - 13,5 + 20,25 =33,25 - 19,5 =13,75
===========================================
lub II sposób:
S5 = a1* = 4* = 4* = 4 * = 1,6*( ) = 440 :32 = 13,75
=================================================================
