Question

If for any A.P. d = 5 then t18 - t13 =
​

Answer 1

Answer:

answer=24

Step-by-step explanation:

common difference = d = 5

first term = a = a

number of the term = n

Tn = a+(n-1)d

T18 = a+(18-1)5

T18 = a+(17)5

T18 = a+85

Tn = a+(n-1)d

T13 = a+(13-1)5

T13 = a+(12)5

T13 = a+60

so,

T18 - T13

= (a+85)-(a+60)

= a+85-a-60

= 85-60

= 25

so 25 is the answer
