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.
