Question

if the sum of three consecutive terms of AP is 48 and the product of first and last term is 252 then find d​

Answer 1

Answer:

Step-by-step explanation:

always the three consecutive number is in the form of (a-d) , a , (a+d)

so the sum of three terms is = 48

(a-d) + a+(a+d) = 48

3a=48

a=48/3

a=16

now the product of first and third term is = 252

(a-d) x (a+d) = 252

a²-d²= 252

(16)²-d²=252

256-d²=252

d² = 256 - 252

d²=4

d=√4

d=2
