Question

*The first four terms of AP for which a = -3, d = 4 are……….*

1️⃣ -3, 1, 5, 9
2️⃣ -3, 2, 5, 9
3️⃣ -3, 1, 4, 9
4️⃣ -3, 1, 5, 8​

Answer 1

Answer:

The four terms are -3,1, 5 , 9

Step-by-step explanation:

Given first term a=-3. , common difference d= 4

the n th term is tn = a+ (n -1)d

second term = -3 +(2-1)4 =-3 +4 =1

third term = -3+(3-1)4 = -3+8 =5

fourth term = -3 +(4-1)4 = 9

so the first four terms are -3 , 1 , 5 , 9
