Find sn for the given arithmetic series a1=-26 d=-9 n=24

- 3108

Step-by-step explanation:

The sum to n terms of an arithmetic series is

= [ 2 + (n - 1)d ]

Substitute the given values into the formula

= [ (2 × - 26) + (23 × - 9) ]

                          = 12 ( - 52 - 207 )

                         = 12 × - 259 = - 3108
