Question

Find 10th term of -1/2,1/2, 3/2

Answer 1

Answer:

a+(n-1)*d

-1/2+(10-1)*-1

-1/2+9*-1

=-1/2-9= -19/2

Answer 2

Answer:

tn=a+(n-1)×d

t1=a=-1/2 t2=1/2

therefore d=t2-t1

that is 1/2-(-1/2)

which is 1/4

to find t10

t10=-1/2+(10-1)*1/4

=-1/2+9/4

which will be 14/8 which will be 7/4
