II) 3rd and 4th numbers are 3 and 4 respectively.
O
Statement I alone is sufficient
Statement | alone is sufficient
Both statements put together are sufficient
Both the statements even put together are not sufficient
Either of the two statements individually is sufficient​

Answer 1

Both statements put together are sufficient

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.
