Question

if a=10 b=10 then write 4 terms of arithmetic progession​

Answer 1

Step-by-step explanation:

if a =10 , d=10

then

t1 = 10

t2=t1 +d = 10+10=20

t3= t2 + d= 20+10=30

t4 = t3+ d= 30+10=40

Answer 2

Answer:

40

Step-by-step explanation:

tn = a + ( n-1 ) d

tn = 10 ( 4 - 1) 10

t4= 10 (3) 10

t4 = 10 + 30

t 4 = 40
