Question

1 The 10th term of the A.P. 13, 8,3,-2...... is:
(A) 32
(B) -54
(C) -57
​

Answer 1

Step-by-step explanation:

a=13,n=10d=-5

using AP formula.

t10=13+(10-1)-5

t10=13+9*-5

t10=13-45

t10=-32

hence 10 th term is -32

Answer 2

Answer

-32

Step-by-step explanation:

a= 13      Common difference(d)= 8 - 13= -5

The nth term= a + (n-1) d

The 10th term= 13 + (10-1) -5

                      = 13 + (9) -5

                      = 13 + (-45)

                      = 13 - 45

                      = -32
