c)1,4,9,....49,...,100
d)1,-5,25,-125,....,15,625​

Answer 1

Răspuns:

Explicație pas cu pas:

a) 1,-2,4,-8,16,....-18   ⇒1;-2;4; -8; 16; -32; 64; -128 (banuiesc ca din viteza ai scris -18 in loc de -128 la sfarsitul acestui sir, altfl sirul nu are logica)

b)1,-3,9,-27,....,729 ⇒1;-3;9;-27;81;-243;729

c)1,4,9,....49,...,100  ⇒1;4;9;16;25;36;49;64;81;100

d)1,-5,25,-125,....,15,625​  ⇒1;-5;25;-125; 625;-3125;15625
