Question

find the sum of five terms of the squence √3,√12,√27

Answer 1

the answer to your question is √3+√12+√27
=>√3+2√3+3√3
=>6√3

Answer 2

here,a=√3
d=a2 -a1
 =√12 -√3 
=2√2-√3
d=√3
n=5
with the formula,
sn = n/2[2a + (n-1)d]
sn = 5/2 [2√3 + (5-1)√3)]
sn =5/2[6√3]
sn=15√2
thus sum of five terms in this AP ,
 =15√3

hope it helps!!!!
