Answer 1

Step-by-step explanation:

$\bf \underline{Question} \:$

find the 17th form form the and of the Arithmeteo

progression

Sion 7, 103.... 184

_____________________________

$\bf \underline{to \: find \to} \:$

the 17th form form the and of the Arithmeteo

progression

_____________________________

$\bf \underline{given \to} \:$

• 7,10,13,.....184

• For finding 7th term from the last we have
• First term = 184

______________________________

$\bf \underline{solution\to} \:$

$\tt \: Common \: difference \: =7-10=-3$

$\bf \huge Now$

$\tt \: {a_7} =a+(7 - 1)d=a+6d \\ </p><p> </p><p> \tt \: {a_7} =184+6 \times -3 \\ </p><p></p><p> \tt \: {a_7} =184-18 \\ </p><p> \tt \red{{a_7} =166}$

Hence 7th term from the last is 166
