Answer 1

$\huge\underline\purple{\mathcal Answer:-}$

any number divide by 4 , and gives remainder three ,

will be in form

4x+3 , where x is more than 1 .

so, our first number will be

4*2+3 = 11 ,

second number ,

4*3+3 = 15

so, on

Now,

near to 300 , last number that satisfy the above condition will be = 299

so, our series is =

11 , 15 , 19, ______________, 299

Tn = a + (n-1)d

299 = 11 + (n-1)4

299-11+4 = 4n

4n = 292

n = 73 (Ans)
