Question

PLEASE SOLVE ASAP WILL GIVE BRAINLIST AND WILL REPORT INCORRECT ANSWERS THANK YOU PLEASE

Answer 1

Answer:

48 and a+(n-1)d

Step-by-step explanation:

21,24

d=t2-t1=24-21=3

t3=a+(2)d=21+6=17

t10=a+(10-1)d=21+(9)3=48

tn=a+(n-1)d

thank you

Answer 2

Answer:

t10= 48 and tn= 90

step by step explanation :

given,

A.P = t1 = 21 and t2= 24

here common difference (d) = t2-t1

= 24 - 21

d = 3

then, t10 = a+(n -1)d

= 21 + ( 10-1)3

= 21+9×3

= 21+27

= 48 ans.

and

tn= a+(n-1)d

t 24= 21 + (24-1)3

t24= 21+ 23×3

t24= 21 + 69

t24= 90 ans.
