Answer
Correct Answer: 346
Explanation
Concept/Approach The sequence is an arithmetic progression (AP) with common difference d = 7.
General term Tn = 10 + (n − 1)·7.
Check options (a) 48: (48 − 10)/7 = 38/7 (not integer) (b) 346: (346 − 10)/7 = 336/7 = 48 (integer) ⇒ in AP (c) 574: (574 − 10)/7 = 564/7 (not integer) (d) 1003: (1003 − 10)/7 = 993/7 (not integer)
Final Answer 346
