Question

The 10th term of the series 13, 8, 3, -2… is

Answer 1

EXPLANATION

• GIVEN

series are = 13,8,3,-2,........

TO FIND 10TH TERM OF AP

Let the first term of series = 13

common difference= b - a

=> 8 - 13 = -5

FORMULA FOR NTH TERM OF SERIES

An = a + ( n - 1 ) d

T10 = a + 9d

13 + 9 (-5)

13 - 45

-32 = ANSWER

Hence,

10th term of Ap = -32

Answer 2

Answer: 58

Step-by-step explanation

d= 8-13=5

a= 13

n=10

T10= from nth term Tn =a+(n-1)d

T10= 13+(10-1)5

=13+(9)5

=13+45=58
