Step-by-step explanation:

1. hi there mate!!!

Solution:

here,

a= first term= 11

d= common difference= 4

now,

according to the formula for finding the nth term,

tn= a+(n-1) ×d

t10= 11+(10-1) ×4

t10= 11+ 9×4

t10= 11+36

t10= 47

hence,

the 10th term= 47

hope this helps!!! ☺❤✌

2.Here's your answer.

Here, a=11.

d=15-11=4.

n=10

So, the term of an A.P. is given by

a+(n-1)d

11+(10-1)4 ==》11+9×4 ==》11+36= 47.

Therefore, the 10th term of the given A.P. is 47.

Answer 2

Given:-

a = 7

d = 4............(11-7)

n = 10

añ = a + (n-1)d

a10 = a + (10-1)d

a10 = a + 9d

a10 = 7 + 9 × 4

a10 = 7 + 36

a10 = 43
