Question

giveme the answerwith out adding 1+3+5+7+9+11​

Answer 1

Answer:

Its an AP whose first term is 1

So, a = 1

and common difference is 2

So, d= 2

The number of terms are 6.

So, n= 6

Now, Sum of AP is given by

Sn = n/2 (2a + (n - 1) d)

= 6/2 (2(1) + (6 - 1 )2)

3 (2 + 10)

36.

Here's the answer!

Answer 2

Answer:

1+ 3 =4 +5=9+9=18 ,11+7=18 so 18 +18=36
