Answer 2

• Both statements put together are sufficient.

• From statements 1 and 2, we get to know that the first four terms are 1, 2, 3, and 4.

• Each term is increasing by 1 and the terms are forming an arithmetic progression.

• The common difference is 1.

• So, the next term or the fifth number will be the fourth term+common difference i.e., 4+1, which is 5.

• Both the statements are necessary to form the A.P.
