Question

Is 101a term of arithmetic sequence 13,24,35....?what about 1001

Answer 1

Answer:

term of an AP. =a+(n-1)d

a=13. d=11 n=101

put a ,d,n value

101. term of AP =13+(101-1)11

=13+100*11

=13+1100

; =1113

now for. 1001 check term of this AP is

1001=13+(n-1)11

1001-13. =(n-1)11

988=(n-1)11

988=n*11-11

988-11. =n*11

977=n*11

977÷11=n

here we get not integer value so it is not a term of anAP
