Question

Is this sequence forms an AP 1,2,4,7,11,16,....... ​

Answer 1

$\huge\mathfrac\red{Hello\:Mate}$

Answer:

$\huge\red{22}$

Hope it helps..

Explanation:

The difference between the numbers is increasing by 1 each time.

Answer 2

Answer:

no

Step-by-step explanation:

the first reason is the difference,i.e. d

thus,d=t2-t1

d=2-1

d=1

thus,d=t3-t2

d=4-2

d=2

since,both differences are not same.thus the sequence is not in AP
