Solve problems 4, 6, and 8 and complete numeric patterns b) and e).

Step 1: Solve problem 4. Let the missing number be x. 18 + x + 12 = 98 Combine the constant terms: 30 + x = 98 Subtract 30 from both sides: x = 98 - 30 x = 68 The missing number is 68. Step 2: Solve problem 6. Let the missing number be y. y - (3 + 5) = 12 First, calculate the sum in the parentheses: y - 8 = 12 Add 8 to both sides: y = 12 + 8 y = 20 The missing number is 20. Step 3: Solve problem 8. Let the missing number be z. 16 - (z ÷ 3) = 4 Subtract 16 from both sides: -(z ÷ 3) = 4 - 16 -(z ÷ 3) = -12 Multiply both sides by -1: z ÷ 3 = 12 Multiply both sides by 3: z = 12 × 3 z = 36 The missing number is 36. Step 4: Complete numeric pattern b). The pattern is 20, 18, 16, 14, This is an arithmetic sequence where each term is 2 less than the previous term. The common difference is -2. The next three terms are: 14 - 2 = 12 12 - 2 = 10 10 - 2 = 8 The completed pattern is 20, 18, 16, 14, 12, 10, 8. Step 5: Complete numeric pattern e). The pattern is 3, 9, 27, This is a geometric sequence where each term is 3 times the previous term. The common ratio is 3. The next three terms are: 27 × 3 = 81 81 × 3 = 243 243 × 3 = 729 The completed pattern is 3, 9, 27, 81, 243, 729. Step 6: Complete the unlabeled numeric pattern starting with 7; 10; . The pattern is 7, 10, This is an arithmetic sequence where each term is 3 more than the previous term. The common difference is 3. The next three terms are: 10 + 3 = 13 13 + 3 = 16 16 + 3 = 19 The completed pattern is 7, 10, 13, 16, 19. Step 7: Complete the unlabeled numeric pattern starting with 16; 14; . The pattern is 16, 14, This is an arithmetic sequence where each term is 2 less than the previous term. The common difference is -2. The next three terms are: 14 - 2 = 12 12 - 2 = 10 10 - 2 = 8 The completed pattern is 16, 14, 12, 10, 8. Send me the next one 📸
