Answer» Answer: Pls mark me Brainliest Step-by-step explanation: let a be the 1st TERM and d be the common difference a8 = a + 7d = 31 a15 = a + 14d = a11 + 16 (a + 10D) + 16 a + 10d +16 = a + 14d = a + 10d +16 = a + 10d + 4d = 16 = 4d d = 16/4 = 4 a + 7d = 31 a + 7(4) = 31 a + 28 = 31 a = 31 -28 = 3 a = 3 , d = 4 ... therefore Ap = a , a+d , a+2d ,a+3d ...... = 3 , 3+4 ,3+2(4) , 3 + 3(4) = 3 , 7 , 11 , 15 ....... ( is your AP)

Answer:

Pls mark me Brainliest

Step-by-step explanation:

let a be the 1st TERM and d be the common difference

a8 = a + 7d = 31

a15 = a + 14d = a11 + 16

(a + 10D) + 16

a + 10d +16 = a + 14d

= a + 10d +16 = a + 10d + 4d

= 16 = 4d

d = 16/4 = 4

a + 7d = 31

a + 7(4) = 31

a + 28 = 31

a = 31 -28 = 3

a = 3 , d = 4 ...

therefore Ap = a , a+d , a+2d ,a+3d ......

= 3 , 3+4 ,3+2(4) , 3 + 3(4)

= 3 , 7 , 11 , 15 ....... ( is your AP)
