Step-by-step explanation:
The answer is
4_

9_

SOLUTION
From the sequence give
–3, 1, 5, 9, . . .
The first term, a = -3
The common difference, d = 4 (gotten by adding 4 to the next term).
The number of terms required n = 6.
Formula for sum of an arithmetic sequence is given by

Substituting these values into the equation above we have

Hence, the answer is 42, option B
Answer:
22
Step-by-step explanation:
