Question 1: D. x is an unknown number here; 7x+3 is an expression, while 7x+3=31 is an equation. Handwritten evidence: The variable x represents an unknown number whose value we are trying to find. The equal sign indicates that the expression on the left side, 7x+3, has the same value as the number on the right side, 31, forming an equation. Question 2: A. N=44; calculate T₆ first, then use N=2T₆+4. Handwritten evidence: Step 1: Calculate T₆ using the term rule Tn=3n+2. T₆ = 3(6)+2 = 18+2 = 20; Step 2: Substitute T₆ into the total formula N=2T₆+4. N = 2(20)+4 = 40+4 = 44 The total N is 44.
