11. It is TRUE because a box has six flat faces and its angles are all right angles.
12. Obviously all prisms are solids, so TRUE.
13. But, not all solids are prisms, so it's a FALSE.
14. Yes, all pyramids are solids, so TRUE.
15. But then again, NOT ALL solids are pyramids, so FALSE.
III.
Since the instruction is "find the 7th term", let us first find the 4th, 5th, and 6th, for us to be able to get the 7th.
16.) 15, 19, 23, 27, 31, 35, 39 (39 is the 7th term)
17.) 13, 23, 33, 43, 53, 63, 73
18.) 29, 27, 25, 23, 21, 19, 17
19.) 0, 5, 10, 15, 20, 25, 30
20.) 9, 21, 33, 45, 57, 69, 81
