1

Problem

Find the value of n,If \$ a = 3 , d = 4 ,a_n = 43 \$

2

Step

The given values

\$ a = 3 , d = 4 ,a_n = 43 \$

3

Formula:

The Arithmetic Progression formula

\$ a_n = a + (n-1)d\$

4

Hint

Substitute \$a,d,a_n\$ values in formula

\$ 43 = 3 + (n-1)4\$

5

Step

After simplification we get

\$ 43 = 3 + 4n - 4\$

6

Step

After simplification we get

\$ 43 = 4n - 1\$

7

Step

After simplification we get

\$ 4n = 43 + 1\$

8

Step

After simplification we get

\$ 4n = 44\$

9

Step

After simplification we get

\$ n = \cancel44^(11)/\cancel4^1\$

10

Step

The value of n is
