Question

Is 310 a term of the A.P. 3, 8, 13, 18.... ?​

Answer 1

Step-by-step explanation:

a=3

d= 8-3=5

an= 310

an=a+(n-1)d

310= 3+(n-1)5

310= 3+5n-5

310=5n-2

312/5=n

n=62.4

as n is not a whole no.

therefore 310 is not a term of this ap

Answer 2

Answer:

First term a=3

Common difference d=5

Tn=a+(n-1)d

310=3+(n-1)5

307=(n-1)5

n=312/5

Which is not a natural number

Hence 310 is not a term in the given AP
