Question

51+52+53+54+55+56+57+58+59+60 =☺☺

Answer 1

Heya mate

The answer of ur question is


A = 51
L = 60
N = 10

So, Sn = 1/2 .n ( a + l )
Sn =1/2 . 10 ( 51 + 60 )
Sn = 5 ( 111)

Sn = 555



So 51 +52 +_ _ _ _ _ _ +60 = 555



hope it helps

Answer 2

Heya mate
The answer is here

Question
51+52+53+54+55+56+57+58+59+60 ...?

Answer

Here
Total number = 10
First number =51 = a
Last number = 60 = l

Sum of a numbers = n / 2 ( a + l )

S10 = 10 /2 ( 51 + 60 )

S10 = 5 ( 111 )

S10 = 555



So , Sum of 10 number = 555 by Sn formula.
