What are the first four terms of the sequence modeled by the recursive formula an=an-1+5 when a1=-3? a) –3, –8, –13, –18 b) –3, 2, 7, 12 c) –3, –15, –75, –375 d) –3, 1, 5, 9

Given sequence:

.

We need to find first four terms of the sequence.

We already given first term -3.

Let us find second term .

Plugging n=2.

Now taking n=3.

.

Now, n=4.

.

We got terms -3, 2, 7 and 12.
