Question

If an ap if third and fourth term 8 and 12 respectively. Find the common difference

Answer 1

common different in an AP :- term2- term1
so,
for common difference by provided information =) 12-8 = 4
C.d. = 4

Answer 2

Answer:

4

Step-by-step explanation:

Let an AP series with common difference d and first term a then the series as given below-

a , a+d , a+2d , a+3d , a+4d

Given that ,

Third term -: a+2d = 8............ (1)

Fourth term-:  a+3d = 12......... (2)

on subtracting equation 1 from equation 2

d = 12 - 8 = 4

then the common difference of the given series is equal to 4.
