Question

find sum of first 10 terms of 4 7 24...?

Answer 1

Hii There!!


Given, a = 4 , d= a2-a1= 7 - 4 => 3 , n = 10 , Sn= ?


Since , we know that, Sum of 'n' terms of an A.P is given by ;

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

=) 10/2 [2(4) + ( 10 -1 ) 3 ]

=) 5 [ 8 + 27 ]

=) 5 [ 35]

Sn=) 175


So, Sum of first 10 terms of an A.P is 175.
