Tentukan 5 suku pertama dari barisan aritmetika berikut? a=-1/2 b=2/3


, = a+(n-1)*b, = -, +(5-1)*, U5 = -1/2+ 4* 2/3, U5 = -1/2 + 8/3, U5 = 13/6
,
U1=a+(n-1)b, =-1/2+(1-1)2/3, =-1/2+0, =-1/2, U2=a+(n-1)b, =-1/2+(2-1)2/3, =-1/2+2/3, = 1/6, U3=a+(n-1)b, =-1/2+(3-1)2/3, =-1/2+4/3, = 5/6, U4=a+(n-1)b, =-1/2+(4-1)2/3, =-1/2+2, = 3/2, U5=a+(n-1)b, =-1/2+(5-1)2/3, =-1/2+8/3, = 13/6
