Answer 1

Answer:

The common difference is 6

The 10th term is 61

Yes, the sum of any 2 terms can be a term of the series. For example 7 + 19 = 25, which is the 4th term.

Step-by-step explanation:

Common difference = Second term - First term

Any term of an AP is = First term + (position of asked term -1) * Common difference.

At the last question, i am not sure. It can be a term of the series. You have written, any term of the series. I think, it should have been any 2 consecutive terms of the series. Then, it would be NO.

Answer 2

Answer:

a) D = 6

b) 10th term = 61

c) YES
