Answer:
22
Step-by-step explanation:
a = -3
second term is - 0.5
third term is 2
common difference = 3rd term - 2nd term
d = 2 -(-0.5) (where d is common difference)
d = 2.5
eleventh term is given by
11 term = a + (n-1)d
where a is 3 , n is 11 , d is 2.5
11 term = -3 + (11-1)2.5
11 term = -3+(10*2.5)
11 term = -3+25
11 term = 22
