Question

write a program to find the following series upto 10 terms:
6,11,16............................

Answer 1

Here is your answer:

a=6

d=5 (a2 -a1)

n=10

an=n/2 (2a+(n-1)d)

a10=10/2 (2(6)+(10-1)5)

= 5 (12 + (9)5)

=5(12+45)

=5(57)

a10=285

up to 10terms is 21,26,31,36,41,46,51,56,61,63.
