Here is a rule for a sequence. After the first two terms, each term is half the sum of the previous two terms
a) Here is a sequence that follows this rule.

12
Write the next three terms.

b) A different sequence follows the same rules.
The 1st term is 5
The 3rd term is 10.5

The accompanying normal probability plot was constructed from a sample of 30 readings on tension for mesh screens behind the surface of video display tubes used in computer monitors. does it appear plausible that the tension distribution is normal? the given probability is has a significant downward curve, so it is plausible that the tension distribution is normal. the given probability is has a significant downward curve, so it is not plausible that the tension distribution is normal. the given probability is quite linear, so it is plausible that the tension distribution is normal. the given probability is has a significant upward curve, so it is not plausible that the tension distribution is normal. the given probability is quite linear, so it is not plausible that the tension distribution is normal.
