Question

Is 250 any term of sequence 3,7,11,15,..... ?

Answer 1

Yes, 250 is a term in this sequence. Follow me for the explanation for this answer.

Thank You.

Answer 2

Answer:

NO

Step-by-step explanation:

Let 250 be the nth term of the sequence.

a = 3, d = 7-3= 4  

therefore,   250 = a + (n-1) d

So, 3 + (n-1) 4 = 250

or,

(n-1)4 = 247

or,

n-1 = 247/4

or,

n=247/4 +1 = 251/4 which is not an integer

Therefore, 250 is not a term of the given A.P.
