an=2+(10)(5)

an=2+50

an=52

Answer 2

Given:

Ap Series = 2,7,12,17,

To Find:

The 11th term in the series

Solution:

As per the series-

a = 2

n = 11

d = a2 - a1

= 7-2

= 5

Using, the formula of AP -

an= a + (n-1) d

Substituting the values -

an = 2  + (11-1) (5)

= 2 +  10 × 5

= 2 + 50

= 52

Answer: The eleventh term of the AP is 52.
