Answer: B

**Explanation:****Question 9.If Sn=2n^2 +3n, then d =**

Answer: C

Put n = 1

=> we get S1 = 5

Put n = 2

=> we get S2 = 14

=>FIRST TERM=S1=5

=>SECOND TERM=S2-S1=14-5=9

=>COMMON DIFF=9-5=4

**Explanation:**Put n = 1

=> we get S1 = 5

Put n = 2

=> we get S2 = 14

=>FIRST TERM=S1=5

=>SECOND TERM=S2-S1=14-5=9

=>COMMON DIFF=9-5=4

**Question 10. If nth term of an AP is given by Tn = 3n + 4, find the common difference of the AP**

Answer: D

**Explanation:**
