Answer:
1032
Step-by-step explanation:
This is an arithmetic sequence (A.P). The sum of an Arithmetic sequence Sn may be expressed as
Sn = n/2(a + l)
where n is the number of terms in the sequence, a is the first term and l is the last term of the sequence.
l = a + (n - 1)d
where d is the common difference between the successive terms of the sequence
132 = -3 + (n - 1) (6 - -3)
132 = -3 + 9n - 9
9n = 132 +12
9n = 144
n = 16
Sn = S16 =16/2( -3 + 132)
= 8 * 129
= 1032
