First term: 180

Second Term: 380

Step-by-step explanation:

In the recursive formula, = any term number and = term. would be the first term, and since it says = -20, our first term would be -20.

means that we have to add 200 to the previous term. Since we're looking for the second term, the previous term was -20. Now, -20 + 200 =  180.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
