Answer:

sum = -30

Step-by-step explanation:

sum of a.p is n/2 [ 2a+(n-1)d]

n = number of terms

a is first term

d is common difference generally a2- a1

in given problem a=-3 and d=0 which means there is no difference among numbers.

given to find sum of first 10 terms

n=10

as per formula 10/2[2(-3)+(10-1)0]

= 5[-6+0]

= 5(-6) = -30

also the a.p will be -3,-3,-3,-3,-3,-3,-3,-3,-3,-3.

by adding it too you get -30.

hope it helps you
