Arithmetic Progressions MCQs

Q1. Which term of the AP -3, -3+2, ... is equal to 7?

• A.6
• B.7
• C.5
• D.8

Answer: A. 6

Q2. In the AP with first term -3 and common difference 2, the number 9 is which term?

• A.7
• B.6
• C.9
• D.8

Answer: A. 7

We are told that -3, 2, 9 (math, chapter 'Arithmetic Progressions'). What we must find: the requested quantity. This is a classic application of therefore the required value = 7. Putting the numbers in: common difference d = a_(n) - a_(n-1) for any AP → therefore the required value = 7. Subtract any two consecutive terms of the given sequence. That lands on option A) 7. As for the others, option B) '6' is wrong because Wrong: uses an incorrect intermediate value; option C) '9' is incorrect: Wrong: a common multi-step slip gives this.

Q3. Which term of the AP -3, -3+2, ... is equal to 13?

• A.8
• B.10
• C.9
• D.13

Answer: C. 9
