Answer:
|
|
Here t1 = 1; t2
=2; t3 = 4 ; t4 = 7 and t5 = 11
|
|
|
|
∴ t2 – t1 = 2 – 1 = 1
|
|
|
|
∴ t3 – t 2 = 4 – 2 = 2
|
|
|
|
∴ t4 – t3 = 7 – 4 = 3
|
|
|
|
∴ t5 – t4 = 11 – 7 = 4
|
|
|
|
∴ Here the difference between any two consecutive
term is go on increasing by 1.
|
|
|
|
∴ t6 = t5 + 5 = 11 + 5 = 16
|
|
|
|
∴ t7 = t6 + 6 = 16 + 6 = 22
|
|
|
|
∴ the next two terms are 16 and 22.
