Question

the first term of an ap of 20 terms is 2 and its last term is 59. find its 16th terms from the end​

Answer 1

Answer:

14

Step-by-step explanation:

first we have to find the common difference (d)

an=a+(n-1)d

59=2+(20-1)d

57=19d

d=57/19=3

the 16th term from last is the 5th term from first,so

an=a+(n-1)d

an=2+(5-1)3

an=2+12

an=14
