Question

find the sum of 2+7/2+5+13/2+... to 10 terms​

Answer 1

How much is 6,24,803 shot of 11,20,000

Answer 2

Answer:

165/2

Step-by-step explanation:

It is the series,

4/2 + 7/2 + 10/2 + 13/2 + ...

So, if we negelate 1/2, then difference between each term is 3.

Formula = (n/2) [ a + (n-1) d ]

n = 10, a = 4 , d = 3

Sum = (10/2) * [ 4 + 9 * 3]

= 5 * 31 = 165

Now, with considering 1/2, answer will be 165/2.
