Solution:
|
Here, t1 = 2, t2 =
5, t3 = 8, t4 = 11
|
Here, t2 – t1 = 5 – 2 = 3
|
t3 – t2 = 8 – 5 = 3
|
t4 – t3 = 11 – 8 = 3
|
Therefore, we can see that the common
difference between any two consecutive terms is 3
|
∴ We can get t5 , t6
, t7 and t8 by adding the common difference 3 to the
preceding term.
|
∴ t5 = t4 + 3 = 11
+ 3 = 14
|
∴ t6 = t5 + 3 = 14
+ 3 = 17
|
∴ t7 = t6 + 3 = 17
+ 3 = 20
|
∴ t8 = t7 + 3 = 20
+ 3 = 23
|
Hence, the next four terms are 14, 17,
20 and 23 respectively.
