Question

The following is a list of numbers forming an AP

1/3, 4/3, 7/3,....What would be the 11th term ?
which term of the AP is the first such number greater than 6 ?​

Answer 1

Answer:

A=1/3

N=11 TH TERM

D=4/3-1/3 = 3/3 = 1

SO , AN=A+(N-1)D

=1/3+(11-1)1

=1/3+10

=31/3

THE TERM GREATER THEN 6 IS

AN>6

》A+(N-1)D>6

》1/3+(N-1)1>6

》1/3+(N-1)>6

》1/3+N-1>6

》1/3-1+N>6

》-2/3+N>6

》N>6+2/3

》N>20/3
