Answer 2

Step-by-step explanation:

Trick for sum of n terms from last

write reverse to the given AP

e g

. 126, 124, 122........ ....... 8

first term = 126

common difference = 124-126= -2

Sn = (n/2)[ 2×126+(n-1) (-2)]

= (n/2)[ 252-2n+2]

= (n/2) [ 254-2n]

Sn = n( 126 - n) is general formula far sum of

last n terms for given AP.
