Question

find 50th term of an AP=-1,1/4,3/2,...​

Answer 1

Answer:

a= -11

d= 4-11=-7

a50= a+(n-1)d

= -11+(50-1)-7

= -11+49×(-7)

= -11+(-343)

= -354

Answer 2

Answer:

Step-by-step explanation:

AP = -1, 1/4, 3/2

Here a = -1

d = 1/4 +1 = 5/4

An = a + (n-1)d

A50 = -1 + (50-1)5/4

= -1 + (49×5/4)

= -1 + 245/4

=241/4

Hope it is clear
