Answer 1

Answer:

38

Step-by-step explanation:

The formula for nth term of an AP is Tn= a + (n-1)d.

where a= first term of AP, d= common difference and n= nth term

d= second term- first term

So, d in this case is 15.5 - 13= 2.5

Applying above formula,

T11= 13+ (11-1)*2.5

T11= 13+ 10*2.5

T11= 13+ 25

T11=38
