• A. 12
• B. 22
• C. 42
• D. 32

Answer 1

Answer:

B. 22

Step 1 Identify the smallest 2-digit number divisible by 4: 12. Step 2 Identify the largest 2-digit number divisible by 4: 96. Step 3 Use the formula for the number of terms in an arithmetic sequence: n = (l - a) / d + 1. Step 4 Substitute the values: n = (96 - 12) / 4 + 1. Step 5 Calculate: n = 84 / 4 + 1 = 21 + 1 = 22. Final Answer: 22
