Question

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

Answer 1

Answer:

No 310 is not a term of given A.P.

Answer 2

Answer:

No

Step-by-step explanation:

A.P.= 3,8,13,18.......

Therefore, First term(a) = 3

Common Difference (d) = a2- a1

= 8-3

=5

Let the nth term of A.P. be 310

a(n) = 310

a + (n-1) d = 310

3 + (n-1) (5) = 310

(n-1) (5) = 310-3

n-1 = 307/5

n = 307/5+1

n = 307+5/5

n = 312/5

Since, 312/5 is not a counting number

Therefore, 310 is not a term of A.P.
