Write the first four terms of the sequence defined by an=20-30(n-1)

The first four terms of sequence is 20, -10, -40, -70

Solution:

Given that we have to find the first four terms of sequence

Given recursive formula is:

To find the first term, substitute n = 1

Thus the first term of sequence is 20

To find the second term, substitute n = 2

Thus the second term of sequence is -10

To find the third term, substitute n = 3

Thus the third term of sequence is -40

To find the fourth term, substitute n = 4

Thus the first four terms of sequence is 20, -10, -40, -70

i think that you should ask google for the answer to that problem because if we don't know it google does

what "following statement"?
