Question

The values of 4+1/4+1/4+1/4+.....n
​

Answer 1

There are n terms in the series. Except first term there are n-1 terms. Adding same number n-1 times is nothing but multiplying that number by number of times given

$4 + \frac{(n - 1)}{4}$

$= \frac{16 + n - 1}{4}$

$= \frac{15 + n}{4}$

Hope this is helpful
