Full solution

Q. What is the next term of the geometric sequence?\newline2,10,502, 10, 50,
  1. Identify Sequence Type: Identify whether the given sequence is geometric or arithmetic.\newlineIn the given sequence, each term after the first is obtained by multiplying the previous term by a constant number, which suggests that the sequence is geometric.
  2. Find Common Ratio: Determine the common ratio of the sequence.\newlineTo find the common ratio, divide the second term by the first term, or the third term by the second term.\newline102=5\frac{10}{2} = 5 and 5010=5\frac{50}{10} = 5\newlineCommon Ratio: 55
  3. Calculate Next Term: Calculate the next term in the sequence using the common ratio.\newlineThe last term given in the sequence is 5050. To find the next term, multiply the last term by the common ratio.\newline50×5=25050 \times 5 = 250
  4. Verify Result: Verify the result to ensure there are no mathematical errors.\newlineThe sequence follows a pattern of multiplication by 55. The progression from 22 to 1010 (2×52 \times 5), and from 1010 to 5050 (10×510 \times 5), correctly leads to the next term being 50×550 \times 5, which is 250250.
